Belgian social security number

[jeffh92]

The Belgian social security identification number is the unique identification number of a person working in or covered for social benefits in Belgium. For Belgian residents, the number is identical to their Belgian National Number (Rijksregisternummer, Numéro National). For non-residents, the number is identical to their Belgian BIS number. Both numbers consists of 11 digits and encode a person's date of birth and gender. It encodes the date of birth in the first 6 digits in the format YYMMDD. The following 3 digits represent a counter of people born on the same date, seperated by sex (odd for male and even for females respectively). The final 2 digits form a check number based on the 9 preceding digits.

This module therefor uses the already existing be.bis and be.nn modules as part of its validation.
