∀ {M₁ : Type u_1} {M₂ : Type u_2} [inst : Mul M₁] [inst_1 : Mul M₂] [IsRightCancelMul M₂] (f : M₁ → M₂),
Function.Injective f → (∀ (x y : M₁), f (x * y) = f x * f y) → IsRightCancelMul M₁A type has right-cancellative multiplication, if it admits an injective map that
preserves * to another type with right-cancellative multiplication.
