Algorithm::CheckDigits::M10_010 - compute check digits for Postscheckkonti (CH) River stage one • 3 direct dependents • 5 total dependents

ALGORITHM 1 The sequence of digits is processed left to right. For the first digit we assume a carry forward of 0. 2 For each digit d(i) the carry forward cf(i) is the digit at the the position p in the sequence ( 0, 9, 4, 6, 8, 2, 7, 1, 3, 5 ), wher...

Algorithm::CheckDigits::MBase_001 - compute check digits for UPC (US) River stage one • 3 direct dependents • 5 total dependents

ALGORITHM 1 Add all digits in odd-numbered positions. 2 Multiply the sum from step 1 with 3. 3 Add all digits in even-numbered positions. 4 Add the product from step 2 and the sum from step 3. 5 If the sum from step 4 is 0 modulo 10, the check digit ...

Algorithm::CheckDigits::MBase_002 - compute check digits for blood bags (DE), BZÜ (DE), VAT Registration Number (DE) River stage one • 3 direct dependents • 5 total dependents

ALGORITHM 1 Start with values P = 10, S = 0. 2 Beginning left you do the following for all digits 1 S = (P + digit) modulo 10 2 If S is 0 then S = 10. 3 P = (2 * S) modulo 11 3 The check digit is (11 - P) modulo 10. METHODS is_valid($number) Returns ...
