st: A STATA code for verification of a check digit
Sorry about sending
this twice I think the first one was too long, so I just sent the link
explaining it in SAS.
Hi! I would
like to know if there is a STATA code to use for verification of a check digit
like the one used in SAS. This applies to the Swedish Personnummer that
everyone has in Sweden. It is comprised of 10 digits (12) if the century
is included. The first 6 are the birth date in YYMMDD followed by a 3
digit birth number and a last digit which is a check digit comprised of the
previous 9 digits calculated by algorithm.
For example, 780924
Here is a
description of how it works in SAS:
