Check Digit Verification of cas no
The CAS Registry Mumber 218767-33-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,7,6 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 218767-33:
(8*2)+(7*1)+(6*8)+(5*7)+(4*6)+(3*7)+(2*3)+(1*3)=160
160 % 10 = 0
So 218767-33-0 is a valid CAS Registry Number.

Studies on the biomimetic synthesis of the manzamine alkaloids
Baldwin,Claridge,Culshaw,Heupel,Lee,Spring,Whitehead
, p. 3154 - 3161 (2007/10/03)
The biomimetic synthesis of the manzamine-related alkaloid keramaphidin B is described. The key intramolecular Diels-Alder reaction proposed in the Baldwin and Whitehead hypothesis is demonstrated. An investigation of the modified biomimetic hypothesis pr
