You don't need to use Less with regular expressions for this one. It is possible to do with pure CSS itself by using attribute selectors like in the below example.

[class*=' col-'] {
  outline: 2px dotted red;
div {
  margin: 10px;
<div class='col-md-11'>Something</div>
<div class='col-md-12'>Something</div>
<div class='col-md-21'>Something</div>
<div class='column-md-11'>Something</div>
<div class='some-class col-md-99'>Something</div>
