On Ring Properties of Injective Hulls

Extract
Let R be an associative ring and denote by the injective hull of the right module RR. If can be endowed with a ring multiplication which extends the existing module multiplication, we say that is a ring and the statement that R is a ring will always mean in this sense.
It is known that is a regular ring (in the sense of von Neumann) if and only if the singular ideal of R is zero.
