The sum rules read $A_{CP}(\\Lambda_c^+\\rightarrow p K^- K^+) + A_{CP}(\\Xi_c^+\\rightarrow \\Sigma^+ \\pi^- \\pi^+) = 0$, $A_{CP}(\\Lambda_c^+\\rightarrow p \\pi^- \\pi^+) + A_{CP}(\\Xi_c^+\\rightarrow \\Sigma^+ K^- K^+) = 0$, and $A_{CP}(\\Lambda_c^+\\rightarrow \\Sigma^+ \\pi^- K^+) + A_{CP}(\\Xi_c^+\\rightarrow pK^-\\pi^+) = 0$.
