فرمول تشخیص صحت کد ملی

همه کدهای ملی ۱۰ رقمی هستند.

کدهای ملی که همه ارقام آنها مثل هم باشند معتبر نیستند مثل  ۲۲۲۲۲۲۲۲۲۲

روش اعتبار سنجی کد ملی :

دهمین رقم شماره ملی را ( از سمت چپ ) به عنوان A در نظر می گیریم.

یک مقدار B در نظر می گیریم و آن را برابر با =

(اولین رقم * ۱۰) + ( دومین رقم * ۹ ) + ( سومین رقم * ۸ ) + ( چهارمین رقم * ۷ ) + ( پنجمین رقم * ۶) + ( ششمین رقم * ۵ ) + ( هفتمین رقم * ۴ ) + ( هشتمین رقم * ۳ ) + ( نهمین رقم * ۲ )

قرار می دهیم.

مقدار C را برابر با = B – (B/11)*11 قرار می دهیم.

اگر مقدار C برابر با صفر باشد و مقدار A برابر C باشد کد ملی صحیح است.

اگر مقدار C برابر با ۱ باشد و مقدار A برابر با ۱ باشد کد ملی صحیح است.

اگر مقدار C بزرگتر از ۱ باشد و مقدار A برابر با ۱۱ – C باشد کد ملی صحیح است.
