We show how relations among various classes of {ital CP} asymmetries in {ital B}{sup 0} decays can be used to test the unitarity of the three-generation Cabibbo-Kobayashi-Maskawa matrix, independently of the mechanism of mixing in the {ital B}{sup 0} and {ital K}{sup 0} systems. We suggest various ways to determine the sign of sin{delta}, independently of the sign of the {ital B}{sub {ital K}} parameter.
