English: IMO numbers that fail the check digit test. Pages here are placed manually.

Sample check for IMO 9241061:

9×7 + 2×6 + 4×5 + 1×4 + 0×3 + 6×2

= 63 + 12 + 20 + 4 + 0 + 12

= 111

111 has a rightmost digit of 1, which is the same as the rightmost digit of the IMO number, so the IMO number passes the checkdigit test.
