Let be a ring. A right -module is said to be retractable if whenever is a non-zero submodule of . The goal of this article is to investigate a ring for which every right R-module is retractable. Such a ring will be called right mod-retractable. We proved that
The ring is right mod-retractable if and only if each is a right mod-retractable ring for each , where is an arbitrary finite set.
If is a mod-retractable ring then is a mod-retractable ring.
