I am not sure I understand your rules, but I think your problem is
(\d\w+){3}. I think this is supposed to correspond to
//first character of inward code must be numeric rule
//second character of inward code must be alpha rule
//third character of inward code must be alpha rule
but what it is really saying is match a numeric character (not [0-9],
but any numeric character*) followed by one or more word characters
(not [a-zA-Z], it includes all non-punctuation and control characters)
three times, that is it will only match strings like "1a2bc3abcdefg".
I believe you want /\d[a-z]{2}/i.
