It's almost always a pain to work with numeric ranges in regex. I
think the best option in this case is to parse sequence as a number
and just use comparison operators. Something like:

var passed = false;
var match = 'C32456'.match(/\d+/);
if (match && match[0]) {
  match = parseInt(match);
}
if (!isNaN(match)) {
 passed = (match > 1234);
}

// etc.
