Invalid checksum of ABN AU (Australia) ACCURACY	AU (Australia)	The Australian Business Number is eleven digits long and consists of a nine-digit identifier preceded by two check digits. This rule verifies the number against those check digits, which are derived with a modulus 89 calculation, meaning the remainder after dividing by 89. For the positions C1 to C11 the weights M11 down to M1 are 10, 1, 3, 5, 7, 9, 11, 13, 15, 17 and 19. The first digit has 1 subtracted from it before being weighted, all weighted values are added together, and for a valid ABN that total modulo 89 is zero. Any other result is flagged.
