Unexpected: Neomycin isn't the main name for its clique

I was looking up an ID for neomycin, and the main label for the clique was Framycetin. It looks like Framycetin (aka neomycin B) is a component of the better-known neomycin.

Thanks for reporting this! The problem is that all the sources we trust most for chemicals (DrugBank, DrugCentral and CHEBI) return both "neomycin" and "Framycetin" (for different identifiers) as the label for this chemical. So I'm not sure how to prefer "neomycin" for this clique. Some options:

1. Choose the numerically smallest identifier suffix (but that won't work in this case, since Framycetin has the smaller DrugBank identifier suffix).
2. Choose the shortest label among the most preferred source ("neomycin" is shorter by one character).
3. Get rid of the chemical preferred name system, and go with the label of the first identifier (in this case, that would give us Neomycin, since it has the lower identifier suffix for CHEBI). We might be able to do that, since Biolink now prefers better names in its prefix order for chemicals anyway.

I'll see if I can come up with some sort of tool we can use to compare different chemical identifier strategies.
