I want to test if a string in javascript contains normal brackets with an integer in it

var str="(12) this is a test";
var pat=/(([\d]+))/;
if (pat.test(str)) 
    alert("true");

Works fine, but it also returns true when the string looks like this

var str="12) test";
var str="(12 test";

which should return false.

    Escape brackets with \:

    /\([\d]+\)/.test(str);
