My version of @Gaby's answer, as I needed a way to check CORS origin against regular expressions in an array:

var corsWhitelist = [/^(?:.+\.)?domain\.com/, /^(?:.+\.)?otherdomain\.com/];

var corsCheck = function(origin, callback) {
  if (corsWhitelist.some(function(item) {
    return (new RegExp(item).test(origin));
  })) {
    callback(null, true);
  } 
  else {
    callback(null, false);
  }
}

corsCheck('otherdomain.com', function(err, result) {
  console.log('CORS match for otherdomain.com: ' + result);  
});

corsCheck('forbiddendomain.com', function(err, result) {
  console.log('CORS match for forbiddendomain.com: ' + result);  
});
