Algebra, chapter X, § 8. Dimension homologique

Suppose AA is left noetherian and of finite homological dimension and let C0\mathscr{C}_0 (resp. C\mathscr{C}) be the set of equivalence classes of finitely generated projective a-modules (resp. of a-modules). Then the canonical homomorphism of Grothendieck groups K(C0)→K(C)K(\mathscr{C}_0) \to K(\mathscr{C}) is bijective.

This follows from X, p. 137, Cor.

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
