Is That Tolkien's Ring Inscription in THE FLASH?

 So, I've now seen the new FLASH movie, and think I spotted a Tolkien reference that went by so quickly I can't be sure. 

In the scene where young Barry receives his iconic ring --the one that holds his superhero costume-- he grins and mutters to himself in what sounded v. much like Black Speech. I think it's the inscription from the ring-verse. Can anyone more conversant with Tolkien's invented languages give this a listen and confirm/deny its identity?
