Converting -1 to uint will not work "((uint)(-1))" solution?

num10 = ((uint)(-1)) >> (0x20 - num9);

Error: Constant value '-1' cannot be converted to a 'uint' (use 'unchecked' syntax to override)

Use 

uint minus1 = unchecked((uint)-1);
uint num10 = (minus1) >> (0x20 - num9);

Or even better

uint num10 = (uint.MaxValue) >> (0x20u - num9);
