validation BBAN hongrois

Question

Quelqu'un peut-il me dire comment valider les numéros de compte BBAN hongrois? sur internet je n'ai trouvé qu'il est de 24 numéros longueur et en format

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

mais comment calculer x = chiffre de contrôle national? J'ai essayé de supprimer le dernier caractère et reste modulo par 97, mais il ne fonctionne pas (le résultat est 1 pour les numéros de compte valides)

merci à l'avance pour toute aide

Answer 1

Je viens de validation de compte hongrois fini fonction. C'est la première version de cette fonction mais ça marche bien.

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++)
