Other than with foot rings used for birds, the chip number itself doesn't tell anything, there is nothing encoded in that chip number - it must be registered somewhere (or at least, written down) to make a connection "this person has something to do with that animal".
Same with other animals: Sometimes people chip their dog or cat, and forget to register them* - then even if the pet is found somewhere, it cannot be attributed to an owner.
So I think if (!) a breeder writes down all the chip numbers of their reptiles, and you just want to check whether your reptile is from them: yes. But otherwise, I don't think so. As registering them, if, is done by the owner as a lost animal should be brought back to the owner, not breeder.
The only thing you could try is IMHO: Check at the next vet visit (or if you know somebody having a chip scanner, e.g. at a pet shelter) whether Ruby is checked. If, then look the number up online where pets are registered. Likely, he's not however as the owner registers them. You might only find a previous owner.
*In Germany it's TASSO, in Chile it's Registro Nacional de Mascotas, but for the US I don't know.
