Check Digit Verification of cas no
The CAS Registry Mumber 26791-73-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,7,9 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 26791-73:
(7*2)+(6*6)+(5*7)+(4*9)+(3*1)+(2*7)+(1*3)=141
141 % 10 = 1
So 26791-73-1 is a valid CAS Registry Number.

Starting from xanthatin, the biomimetic synthesis of 4b,5b-epoxyxanthatin-1a,4a-endoperoxide, a novel monomeric xanthanolide, has been achieved. Moreover, four unprecedented xanthanolide dimers were synthesized by three different dimerizations of xanthatin, either in a head-tohead or head-to-tail fashion. Notably, these dimeric compounds were firstly identified as artifacts in the laboratory, and two of them, mogolides A and B, proved to be natural products present in the Xanthium mogolium Kitag plant.
