hmm check boxes are the best way i could think off , even though it had the disadvantage u mentioned
(if check boxes are set up there's must be some scrip to check compound invalid if none of the alchemy type is chosen)

for last idea as u said doing calculations may not work for weird compounds and we still dont know all these alchemy laws its still in a learning process, so these "exceptional compounds" are the key to learn new/unknown "laws" of alchemy

edit
--- little hard to read icons , kinda looks similar from distance
