devAs देवास् + **Ucus ऊचुस्

→ devA देवा + y य् + UcuH ऊचुः by this rule

The y य् can stay as y य्, or it can be replaced with /laghu-prayatna-tara by vyorlaghupray... >, or with hiatus by lopazzAkaly... >>.

Some people say that it MUST be replaced with either /laghu-prayatna-tara or hiatus.

In print it is always replaced with hiatus. In chanting it is often replaced with y य्.
