title: RegEx for ISIN with at least 1 number
body: <p>I have the following RegEx to parse ISIN of bonds, assets, etc.. (2 characters followed by 10 digits and characters)</p>
  <pre><code>([A-Z]{2})([A-Z0-9]{10})
  </code></pre>
  <p>But this also marks for example a word like this <code>ABCDEFGHIJKL</code>, but this is no real ISIN. A definition of ISINs is here: <a href="https://en.wikipedia.org/wiki/International_Securities_Identification_Number" rel="nofollow noreferrer">WIKI</a></p>
  <p>So some examples are <code>US45256BAD38</code>, <code>US64118Q1076</code>, <code>XS0884410019</code>. What would be the correct RegEx to search for them, without matches like <code>ABCDEFGHIJKL</code>?</p>
  <p>Maybe with a RegEx to have at least one number?</p>
