下面是我用维基百科文章中的例子快速写出来的东西。
不能保证完美或无bug或超级高效，但应该为您提供一个坚实的起点：

注意：我在下面包含了Confluence提供的编辑，使程序稍微更简洁。

function validate_vin($vin) {

    $vin = strtolower($vin);
    if (!preg_match('/^[^\Wioq]{17}$/', $vin)) { 
        return false; 
    }

    $weights = array(8, 7, 6, 5, 4, 3, 2, 10, 0, 9, 8, 7, 6, 5, 4, 3, 2);

    $transliterations = array(
        "a" => 1, "b" => 2, "c" => 3, "d" => 4,
        "e" => 5, "f" => 6, "g" => 7, "h" => 8,
        "j" => 1, "k" => 2, "l" => 3, "m" => 4,
        "n" => 5, "p" => 7, "r" => 9, "s" => 2,
        "t" => 3, "u" => 4, "v" => 5, "w" => 6,
        "x" => 7, "y" => 8, "z" => 9
    );

    $sum = 0;

    for($i = 0 ; $i < strlen($vin) ; $i++ ) { // loop through characters of VIN
        // add transliterations * weight of their positions to get the sum
        if(!is_numeric($vin{$i})) {
            $sum += $transliterations[$vin{$i}] * $weights[$i];
        } else {
            $sum += $vin{$i} * $weights[$i];
        }
    }

    // find checkdigit by taking the mod of the sum

    $checkdigit = $sum % 11;

    if($checkdigit == 10) { // checkdigit of 10 is represented by "X"
        $checkdigit = "x";
    }

    return ($checkdigit == $vin{8});
}

注意：由于校验和的性质，验证VIN时会有很小的百分比错误：

匹配并不能证明VIN是正确的，因为任何两个不同的VIN仍然有1/11的机会具有匹配的校验位。

另请注意：11111111111111111将根据上述过程进行验证。是否要检查，取决于您：

直的1（17个连续的1）将满足校验位。这是因为值1乘以89（权重之和）仍然是89。而89%11是1，校验位。这是测试VIN检查算法的简单方法。

下面是一个由jordan移植到Javascript的代码版本，希望对某人有帮助。

function validate_vin(vin)
{
  function isnumeric(mixed_var) {
    return (typeof(mixed_var) === 'number' || typeof(mixed_var) === 'string') && mixed_var !== '' && !isNaN(mixed_var);
  }
  var pattern = /^[^\Wioq]{17}$/;
  var weights = Array(8, 7, 6, 5, 4, 3, 2, 10, 0, 9, 8, 7, 6, 5, 4, 3, 2);
  var transliterations = {
    "a" : 1, "b" : 2, "c" : 3, "d" : 4,
    "e" : 5, "f" : 6, "g" : 7, "h" : 8,
    "j" : 1, "k" : 2, "l" : 3, "m" : 4,
    "n" : 5, "p" : 7, "r" : 9, "s" : 2,
    "t" : 3, "u" : 4, "v" : 5, "w" : 6,
    "x" : 7, "y" : 8, "z" : 9
  };

  vin = vin.toLowerCase();
  if(!vin.match(pattern)) { return false; }

  var sum = 0;
  for(var i=0; i<vin.length; i++) {
    if(!isnumeric(vin.charAt(i))) {
      sum += transliterations[vin.charAt(i)] * weights[i];
    } else {
      sum += parseInt(vin.charAt(i)) * weights[i];
    }  
  }

  var checkdigit = sum % 11;
  if(checkdigit == 10) { // check digit of 10 represented by X
    checkdigit = 'x';
  }

  return (checkdigit == vin.charAt(8));
}

是“VIN”，“VIN Number”=“Vehicle Identification Number Number Number”，这没道理。
您可以在此处查看VIN结构的定义：
http://en.wikipedia.org/wiki/Vehicle_identification_number
你可以从那里开始工作，或者你可以在这里获取这个脚本：
http://www.geekpedia.com/code29_Check-if-VIN-number-is-valid.html
下面是jordan发布的函数的改进版本：

$vin = "1M8GDM9AXKP042788";

function validate_vin($vin) {

    $vin = strtolower($vin);
    if (!preg_match('/^[^\Wioq]{17}$/', $vin)) { 
        return false; 
    }

    $weights = array(8, 7, 6, 5, 4, 3, 2, 10, 0, 9, 8, 7, 6, 5, 4, 3, 2);

    $transliterations = array(
        "a" => 1, "b" => 2, "c" => 3, "d" => 4,
        "e" => 5, "f" => 6, "g" => 7, "h" => 8,
        "j" => 1, "k" => 2, "l" => 3, "m" => 4,
        "n" => 5, "p" => 7, "r" => 9, "s" => 2,
        "t" => 3, "u" => 4, "v" => 5, "w" => 6,
        "x" => 7, "y" => 8, "z" => 9
    );

    $sum = 0;

    for($i = 0 ; $i < strlen($vin) ; $i++ ) { // loop through characters of VIN
        // add transliterations * weight of their positions to get the sum
        if(!is_numeric($vin{$i})) {
            $sum += $transliterations[$vin{$i}] * $weights[$i];
        } else {
            $sum += $vin{$i} * $weights[$i];
        }
    }

    // find checkdigit by taking the mod of the sum

    $checkdigit = $sum % 11;

    if($checkdigit == 10) { // checkdigit of 10 is represented by "X"
        $checkdigit = "x";
    }

    return ($checkdigit == $vin{8});
}

我最近不得不用PHP编写一个VIN验证类。我发布了我的类供大家使用：http://dev.strategystar.net/2012/05/validate-vin-checksum-with-php/

class VIN
{
    public static $transliteration = array(
        'A'=>1, 'B'=>2, 'C'=>3, 'D'=>4, 'E'=>5, 'F'=>6, 'G'=>7, 'H'=>8, 
        'J'=>1, 'K'=>2, 'L'=>3, 'M'=>4, 'N'=>5, 'P'=>7, 'R'=>9,
        'S'=>2, 'T'=>3, 'U'=>4, 'V'=>5, 'W'=>6, 'X'=>7, 'Y'=>8, 'Z'=>9,
    );

    public static $weights = array(8,7,6,5,4,3,2,10,0,9,8,7,6,5,4,3,2);

    /***
     * The checksum method is used to validate whether or not a VIN is valid
     * It will return an array with two keys: status and message
     * The "status" will either be boolean TRUE or FALSE
     * The "message" will be a string describing the status
     */
    public static function checksum($vin)
    {
        $vin = strtoupper($vin);
        $length = strlen($vin);
        $sum = 0;

        if($length != 17)
        {
            return array('status'=>false, 'message'=>'VIN is not the right length');
        }

        for($x=0; $x<$length; $x++)
        {
            $char = substr($vin, $x, 1);

            if(is_numeric($char))
            {
                $sum += $char * self::$weights[$x];
            }
            else
            {
                if(!isset(self::$transliteration[$char]))
                {
                    return array('status'=>false, 'message'=>'VIN contains an invalid character.');
                }

                $sum += self::$transliteration[$char] * self::$weights[$x];
            }
        }

        $remainder = $sum % 11;
        $checkdigit = $remainder == 10 ? 'X' : $remainder;

        if(substr($vin, 8, 1) != $checkdigit)
        {
            return array('status'=>false, 'message'=>'The VIN is not valid.');
        }

        return array('status'=>true, 'message'=>'The VIN is valid.');
    }
}

请注意，wiki说：“在美国和加拿大销售的所有道路车辆都使用校验位验证。”
因此，如果你与其他国家合作，你可能想放松校验位验证

感谢所有的算法等等。我在维基百科上看到的。这是我根据上面的评论整理的版本。注意，上面的版本有问题，例如00000000000354888对vin返回OK。我采取了上面的内容，并添加了一个选项，如果〈1980，则首先检查年份，假设它不是一个17位的真实的vin（必须），并且如果有单个字符的序列，则假设无效。这对于我的需要来说已经足够好了，因为我正在与长度为0（如果不是17）的值进行比较。我也知道年份的值，所以如果我检查，我可以加快代码跳过VIN检查（是的，我可以把它在函数之前）哈哈再见！.

以下是Mike Q发布的JavaScript类版本：

真的很喜欢bimbom22代码，但在php 8.1.18更新后抛出此错误：PHP致命错误：不再支持带大括号的数组和字符串偏移量访问语法
以下是更新后的语法，以解决php 8.1.18中的致命错误
