title: Exclude a certain number from this regex
body: <p>I have this regex that test for an input with max length of 5. My problem is I want to exclude the single digit of 2. If string contains only number "2", it should fail. How do I exclude number 2 in this regex? <code>/^([a-zA-Z,\d]){1,5}$/</code> <br/></p>
  
  <p>13425 - Match <br />
  03277 - Match <br />
  2 - Fail.</p>
