Commutative Algebra, chapter VIII, § 1. Dimension de Krull d’un anneau

Suppose A is an integral domain and finite-dimensional. Put d=dim⁡(A)d = \dim(A). Then we have C≤d=C\mathscr{C}_{\leq d} = \mathscr{C}, Zd=Z.[Spec(A)]=Z0Z_d = \mathbf{Z}.[\mathrm{Spec}(A)] = Z^0, zd(M)=rg(M).[Spec(A)]=z0(M)z_d(M) = \mathrm{rg}(M).[Spec(A)] = z^0(M), and the modules of type C≤d−1\mathscr{C}_{\leq d-1} are the torsion modules.

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