title: Use regex to verify an ISBN number
body: <p>I need a regex to verify ISBN number entered by user.</p>
  
  <p>ISBN must be a string contains only:
  <code>[10 or 13 digits] and hyphens</code></p>
  
  <p>I tried <code>^[\d*\-]{10}|[\d*\-]{13}$</code> but it doesn't work.</p>
  
  <p>My regex only matches: <code>978-1-5661</code>, <code>1-56619-90</code>, <code>1257561035</code></p>
  
  <p>It should returns the results below:</p>
  
  <pre><code>"978-1-56619-909-4 2" =&gt; false
  "978-1-56619-909-4" =&gt; true
  "1-56619-909-3 " =&gt; false
  "1-56619-909-3" =&gt; true
  "isbn446877428ydh" =&gt; false
  "55 65465 4513574" =&gt; false
  "1257561035" =&gt; true
  "1248752418865" =&gt; true
  </code></pre>
  
  <p>I really appreciate any help.</p>
