Let R be an Artinian ring (not necessarily with unit element), let Z(R) be its center, and let R° be the group of invertible elements of the ring R with respect to the operation a ∘ b = a + b + ab. We prove that the adjoint group R° is nilpotent and the set Z(R) + R° generates R as a ring if and only if R is the direct sum of finitely many ideals each of which is either a nilpotent ring or a local ring with nilpotent multiplicative group.
