My SIN didn't check out with this algorithm, either. I think that the problem
is that the ODD digits, not the even ones, should be doubled.

I've also heard that the first digit of the SIN indicates the province where
you applied for the card. My SIN starts with '4' for Ontario. I have a friend
whose SIN starts with '6' for Manitoba. Can anyone shoot this theory down?
