What does sare di cassa mean in portugeese and I do not knowif how to spell it?

It seems you're trying to translate "saré di cassa" from Italian into Portuguese. However, "saré di cassa" is not a valid Italian phrase. It appears you might be mistaking it for something else.

Could you clarify what you're looking for? Maybe you're thinking of:

* "Sare di cassa" (Italian for "box salt", a type of salt used in curing meats)

* "Sare di cassa" (Italian for "cash drawer" or "till")

* "Sare di cassa" (Italian for "box salt" or "box cash")

Once you provide more context, I can give you a more accurate translation into Portuguese.
