Is my Casio fx-7400GII allowed for the SAT ?

I think that even TI-84 PLUS CE-T are allowed in the SAT. So yeah, even graphic programmable calculators are allowed.  At least I remember going with one lol. 
Still, for an optimal result, Google is your friend: SAT Calculator Policy + List of Approved Calculators (collegevine.com)

thanks :) It's allowed
