Yes. Setting up links can be complex due to the large number of catalog vendors and product lines, so the WorldCat Registry features automatic suggestions for the URL syntaxes used in deep linking based on a sample link you provide.
Be sure to test suggested links before saving them to your Registry profile. A successful test should display your ILS interface and, within it, your local record for the test item. If you do not hold the item, whatever message or interface facility your ILS employs for "record not found" should be displayed. You can change the test record to one that your institution owns for the best test.
