The French ID numbers (INSEE) are wrong:
here's an example : (Elia Gaillard),2NNaN51189076 93
1) the 2 is correct (female; 1 for male)
2) NNaN should be 7703 since she was born on 23 mars 1977
3) The final 93 should be 13. This 2 digit key is computed as follows for a number NNNNNNNNNNNNN:
KK = 97 - ( ( NNNNNNNNNNNNN ) mod 97 )
