Let R be an Auslander‐regular, Cohen‐Macaulay, Noetherian ring that is stably free. Then, we prove that R is a domain and a maximal order in its division ring of fractions. In particular, this applies to the Sklyanin algebra S and shows that, when S satisfies a polynomial identity, it is actually a finite module over its centre.
