Error-correcting codes are important for the improvement of efficiency and security in information transmission. Constructing codes with good parameters is a fundamental problem in error-correcting codes. In this paper
we mainly study self-dual constacyclic codes over the finite nonchain ring

including Euclidean self-dual constacyclic codes
Hermitian self-dual constacyclic codes and maximal distance separable (MDS) codes of Hermitian se
lf-dual constacyclic codes. We give a necessary condition for constacyclic codes to be Euclidean self-dual and give a necessary and sufficient condition for constacyclic codes to be Hermitian self-dual over the ring
