12 # 4, 12 # 5 how to use regular matching the 12 # 3 # 4 # 5?
How do you write this format of regular

/^ 12 # [3-9] $/
Test begin with 12 # to middle [3-9] a at the end of the string in the middle

Regular is simple is the premise of clear requirements,

It is best to say a few examples and say which part to match
