匈牙利BBAN验证

Question

任何人都可以告诉我如何验证匈牙利BBAN账号numbres吗？ 在互联网上我只发现它是24个数字长度 格式

bbbs sssk cccc cccc cccc cccx
b = National bank code
s = Branch code
c = Account number
x = National check digit

但如何计算x =国家校验位？ 我试图删除最后一个字符和模数休息97但它不起作用 （有效帐号的结果不是1）

提前感谢任何帮助

我刚刚完成匈牙利帐户验证功能。这是此功能的第一个版本，但它运行良好。

public string sprawdzWegierskitempAccountNumber(string _accountNumberToCheck, bool _iban) //if iban is true then function result will be always IBAN (even if _accountNumberToCheck will be BBAN) { string _accountNumberCorrected = _accountNumberToCheck.Replace(" ", ""); _accountNumberCorrected = _accountNumberCorrected.Replace("-", ""); _accountNumberCorrected = _accountNumberCorrected.Replace("//", ""); _accountNumberCorrected = _accountNumberCorrected.Replace("\", ""); string _accountNumberCorrectedFirst = _accountNumberCorrected; if (_accountNumberCorrected.Length == 16 || _accountNumberCorrected.Length == 24 || _accountNumberCorrected.Length == 28) {

        if (_accountNumberCorrected.Length == 28) //IBAN Account number
        {
            _accountNumberCorrected = _accountNumberCorrected.Substring(4, _accountNumberCorrected.Length - 4); //we don't need first four digits (HUxx)
        }

        string digitToMultiply = "9731";
        int checkResult = 0;

        //checking first part of account number
        for (int i = 0; i <= 6; i++)
        {
            checkResult = checkResult + int.Parse(_accountNumberCorrected.ToCharArray()[i].ToString()) * int.Parse(digitToMultiply.ToCharArray()[i % 4].ToString());
