title: Regular expression for phrase contain literals and numbers but is not all phrase as a number only with fixed range length
body: <p>i want to have regular expression to check input character as <code>a-z</code> and <code>0-9</code> but i do not want to allow input as just numeric value at all ( must be have at least one alphabetic character)</p>
  
  <p>for example :</p>
  
  <p><code>413123123123131</code><br><br>
  not allowed but if have just only one alphabetic character in any place of phrase it's ok
  <br>i trying to define correct Regex for that and at final i raised to </p>
  
  <p><code>[0-9]*[a-z].*</code><br><br>
  but in now i confused how to defined <code>{x,y}</code> length of phrase i want to have <code>{9,31}</code> but after last <code>*</code> i can not to have length block too i trying to define group but unlucky and not worked </p>
