"Case
(
result =11;... "

That's NOT going to happen.

I think this could be simplified to =

Let ( [
p = Sum (
5 * Middle ( CUIT ; 1 ; 1 ) ;
4 * Middle ( CUIT ; 2 ; 1 ) ;
3 * Middle ( CUIT ; 3 ; 1 ) ;
2 * Middle ( CUIT ; 4 ; 1 ) ;
7 * Middle ( CUIT ; 5 ; 1 ) ;
6 * Middle ( CUIT ; 6 ; 1 ) ;
5 * Middle ( CUIT ; 7 ; 1 ) ;
4 * Middle ( CUIT ; 8 ; 1 ) ;
3 * Middle ( CUIT ; 9 ; 1 ) ;
2 * Middle ( CUIT ; 10 ; 1 )
)
] ;
Case ( Middle ( CUIT ; 11 ; 1 ) = Mod ( -p ; 11 ) ; "Correcto" ; "Error" )
)

Thanks, you're right the simplified version looks nicer. The previous one I posted was the "work in progress". Thanks a lot!
