Quite a while ago I have seen a formula to validate a given SIN number. Unfortunately, I have not saved it. Can someone send it to me or post it out again ? Thanks in advance. Vincent Ng School of Computing Science Simon Fraser University Burnaby. B.C.

Let c1, c2, c3, c4, c5, c6, c7, c8, and c9 be the successive digits of a SIN from left to right. If the following sum is a multiple of 10, the SIN is a valid one. c1 + c3 + c5 + c7 + c9 + s2 + s4 + s6 + s8 where, | 2 ci if ci < 5 si = | | 2 (ci - 4) - 1 if ci > 4
