* method name : IDCardValidate description : ID card number verification 1. Number structure
* Citizen ID number is a feature combination code, which consists of seventeen-digit body code and one-digit verification code. The arrangement order from left to right is: six-digit address code,
* Eight-digit date of birth code, three-digit sequence code and one-digit check code. 2. Address code (the first six digits)
* Indicates the administrative division code of the county (city, banner, district) where the permanent residence of the coding object is located, and is implemented in accordance with the provisions of GB/T2260. 3. Date of birth code (seventh to fourteenth digits)
* Indicates the year, month, and day of the birth of the coding object, which is implemented in accordance with the provisions of GB/T7408, and there is no separator between the year, month, and day codes. 4. Sequence code (15th to 17th digits)
* Indicates the sequence numbers assigned to people born in the same year, month, and day within the area identified by the same address code. The odd number of the sequence code is assigned to males, and the even numbers are assigned to females. 5. Check code (18th digit)
* (1) The weighted summation formula of the seventeen-digit ontology code S = Sum(Ai * Wi), i = 0, ... , 16 , first sum the weights of the first 17 digits
* Ai: represents the ID number value at the i-th position Wi: represents the weighting factor at the i-th position Wi: 7 9 10 5 8 4 2 1 6 3 7 9 10 5 8 4
* 2 (2) Calculate the modulo Y = mod(S, 11) (3) Obtain the corresponding check code Y through the modulo: 0 1 2 3 4 5 6 7 8 9 10 Check code: 1 0
