Let A be a Koszul Artin-Schelter regular algebra and an algebra homomorphism from A to . We compute the Nakayama automorphisms of a trimmed double Ore extension [introduced in Zhang and Zhang (J Pure Appl Algebra 212:2668-2690, 2008)]. Using a similar method, we also obtain the Nakayama automorphism of a skew polynomial extension , where is a graded algebra automorphism of A. These lead to a characterization of the Calabi-Yau property of , the skew Laurent extension and with a diagonal type.
