ハンガリーのBBANの有効性確認

Question

誰でもハンガリーのBBANアカウントの番号を検証する方法を教えていただけますか？ は、インターネット上で、私は、それが24個の数字長 であることを発見したと形式で

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

が、x =国立チェックデジットを計算する方法？ は（結果は有効なアカウント番号の1ではありません）私は97で最後の文字とモジュロ残りを削除しようとしていますが、それは 動作しない任意の助け

Answer 1

を事前に

おかげで私はハンガリーのアカウントの検証を終えました関数。これはこの関数の最初のバージョンですが、うまくいきます。あなたが探しているチェックデジットを計算するためのアルゴリズムとして_HungarianバンキングAssociation_に連絡する必要があるかもしれません
