Has anyone done the cryptoarithmetic problem: "CROSS + ROADS = DANGER" ?

BTW, the answer to the 12 coin problem is three weighings and you can tell
which one is heavier or lighter. I don't know how it's done. THe best I 
could come up with is 3 or 4 depending on what you get on your first weighing.
