ID card number encoding principle: Number Structure A citizenship number is a combination of features and consists of a 17-digit ontology code and a verification code. The six-digit address code, eight-digit birth date code, three-digit sequence code, and one-digit verification code are arranged from left to right. Verification code calculation (1) 17-digit ontology weighted sum formulaS = sum (ai * WI), I = 0,..., 16, first to the front17-digit weigh
