Here, we present a study of B- → D0CPK- decays, where D0CP is reconstructed in CP-even channels, based on a sample of 88.8 × 106 $$\Upsilon$$(4S) → B$$\overline{B}$$ decays collected with the BABAR detector at the PEP-II e+e- storage ring. We measure the ratio of Cabibbo-suppressed to Cabibbo-favored branching fractions $$\mathscr{B}$$(B- → D0CPK-)/$$\mathscr{B}$$(B- → D0CPπ-) = [8.8 ± 1.6(stat) ± 0.5(syst)] × 10-2 and the CP asymmetry ACP = 0.07 ± 0.17(stat) ± 0.06(syst). We also measure $$\mathscr{B}$$(B- → D0K-)/$$\mathscr{B}$$(B- → D0π-) = [8.31 ± 0.35(stat) ± 0.20(syst)] × 10-2 using a sample of 61.0 × 106 B$$\overline{B}$$ pairs.
