Method Detail

passesMod11Test

public static boolean passesMod11Test(List<Integer> digits,
                                      int multiplier)

Check if the input passes the mod11 test

Parameters:

digits - The digits over which to calculate the mod 11 algorithm

multiplier - the multiplier for the modulo algorithm

Returns:

true if the mod 11 result matches the check digit, false otherwise

passesMod10Test

                                      int multiplier)

Mod10 (Luhn) algorithm implementation

Parameters:

digits - The digits over which to calculate the checksum

multiplier - Multiplier used in the algorithm

Returns:

true if the mod 10 result matches the check digit, false otherwise
