Can a defendant argue that his concurrent sentence violates section 654 of the Criminal Code?

Defendant's arguments are both foreclosed by his plea agreement and rule 4.412, which states as follows: "By agreeing to a specified prison term personally and by counsel, a defendant who is sentenced to that term or a shorter one abandons any claim that a component of the sentence violates section 654's prohibition of double punishment, unless that claim is asserted at the time the agreement is recited on the record." Rule 4.412 applies to a contention that concurrent terms violate section 654. (People v. Valenzuela (1993) 14 Cal.App.4th 837, 841.)
