Check Digit Verification of cas no
The CAS Registry Mumber 218271-67-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,2,7 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 218271-67:
(8*2)+(7*1)+(6*8)+(5*2)+(4*7)+(3*1)+(2*6)+(1*7)=131
131 % 10 = 1
So 218271-67-1 is a valid CAS Registry Number.

Synthesis of a monocyclic core of the antifungal sordarins
Cuevas, Juan C.,Martos, Jose L.
, p. 8553 - 8556 (1998)
An enantiospecific synthesis of a monocyclic core of the antifungal sordarins and sordaricins has been achieved. This synthesis is based on the conversion of (+)-3,9-dibromocamphor into a 1,1,2,2,5-pentasubstituted cyclopentane bearing all the key functionalities present in these antifungals.
