5 days in a row can be tough to maintain over the course of time, it can slowly wear you down. It's also a little tough to make a decent split without having overlap. Example...biceps are still healing and it's now back day, and don't forget that triceps are heavily involved on chest day and shoulder day. If you really want to go with 5 days in a row then I would definitely take Saturday and Sunday off so that your nervous system gets a rest.

I would arrange the days like this instead....

Monday.......Back
Tuedsay......Chest
Wednesday..Legs
Thursday.....Shoulders
Friday.........Arms

This way your lower back has a little time to rest before you squat. You have questionable choices of shoulder exercises though. Behind the neck presses and upright rows can both be a rotator cuff grinder. If you have access to a leg press I would choose it over leg extensions. It seems a lot of people do better with SLDL over leg curls, but I personally prefer doing leg curls.
