Algebra, VIII, p. 224, § 12. Tensor Products of Semisimple Modules

Let L be a separable extension of K. We have R(A(L))=\mathfrak{R}(A_{(L)}) = R(A)(L)\mathfrak{R}(A)_{(L)} if L is algebraic over K or if the ring A is left Artinian.

This is the case M=AsM = A_s of Proposition 10.

Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
