A five second glance raises the following issue:

#1 you are using a regex to validate credit card numbers:

/^3(?:[47]\d([ -]?)\d{4}(?:\1\d{4}){2}|0[0-5]\d{11}|[68]\d{12})$|^4(?:\d\d\d)?([ -]?)\d{4}(?:\2\d{4}){2}$|^6011([ -]?)\d{4}(?:\3\d{4}){2}$|^5[1-5]\d\d([ -]?)\d{4}(?:\4\d{4}){2}$|^2014\d{11}$|^2149\d{11}$|^2131\d{11}$|^1800\d{11}$|^3\d{15}$/

This is a valid CC number: 6372178847694560
This is NOT a valid CC number: 6372178847694506

Compare your approach to the use of the Luhn Formula.
