Hints to help you

(?i)  means case insensitive
[a-z] means a single lower case alpha char
[A-Z] means a single upper case alpha char
[0-9] means a single digit

(?i)^[a-z][0-9]\.[a-z][0-9][0-9][a-z][a-z]\.[0-9][0-9]$
means
upper or lower case for all matches
\. means a literal period character
^ means a match must start at the beginning of a line
$ means a match must stop at the line ending char

thus the matching string must have the same alpha-numeric positions  
and be the same length,
white space not allowed, nor commas, quotes, and other punctuation.

RegEx used to be Greek to me, but then I discovered it does not even  
closely resemble Greek.
