Integers can also be negative. Not sure if this applies to your case but 
if so, change the regex to something like:

match = '-000345'.match(/^\-*\d+$/) # MatchData
match[0] # "-000345"

match = '000345'.match(/^\-*\d+$/) # MatchData
match[0] # "000345"

match = '0003b45aa'.match(/^\-*\d+$/) # nil
match # nil
