Description
This is for the Finnish social security numbers (henkilötunnus / hetu). It consists of eleven characters of the form DDMMYYCZZZQ, where DDMMYY is the date of birth, C the century sign (-,+, or A), ZZZ the individual number (even for men and odd for female), and Q the control character or the checksum. It is calculated DDMMYYZZZ mod 31, where the remainder 0,1,2,..,31 is converted from the list 0,1,...A,B,C..Y . The G,I, O and Q are not in the list, they are too similar to numbers 1, 8 and 0 (zero). Note: This regex does not calculate the checksum (mod 31).
