I can't speak to the specifics of chemistry, but I will mention what a department advisor once told me: Always remember that departmental requirements are not designed to precisely match the entrance requirements of your dream school.
I had been considering applying to medical school, and had to deal with the English and math requirements. I had taken one of my semesters of college English as an AP course, and has taken both my semesters of calculus as a community college sequence while still in high school. Despite that, I could have still applied and potentially gotten in, particularly at a less than ideal choice, since I did technically meet the requirements. But it just wouldn't have looked as good.
I'm imagining your situation may be quite similar in that regard.
