Second, the replacement card number that you assign must be a
valid card number. That is, if you are using Modulus-10 to
calculate the check-digit of your account numbers, then the
check-digit of the replacement card number that you have
assigned must be correct. CardLinK uses Modulus-10 to validate
card numbers if the parameter field CHECK DIGIT METHOD
located in the Page 9 screen of PCIT (Type Record Inquiry) is set
to a code equivalent to ‘1’.
