I want to know whether Inulicin is same with 1-O-acetylbritannilactone or not.

Some say it's synonym, the other say differnt.

CAS Number: 681457-46-5, 33627-41-7

What is the structure of Inulicin?
What is the structure of 1-O-acetylbritannilactone?

Sorry for my poor English

If two compounds have different CAS registry numbers, then they are different compounds.

CSI finder says "Inulicin's CAS number is 33627-41-7 and 681457-46-5 is deleted CAS number."

So I find the structure of 33627-41-7, but the structure is not the only one at many web-sites.

Not necessarily. Although the same CAS number should indicate the same compound, the reverse is not always true - it could just mean from a different (natural) source in this case, for instance.
