Check Digit Verification of cas no
The CAS Registry Mumber 10438-17-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,3 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 10438-17:
(7*1)+(6*0)+(5*4)+(4*3)+(3*8)+(2*1)+(1*7)=72
72 % 10 = 2
So 10438-17-2 is a valid CAS Registry Number.

Five monomeric and seven quasi-dimeric indole alkaloids were isolated from the leaves of Cinchona ledgeriana, five are known; the structures of two novel quasi-dimeric alkaloids have been elucidated by chemical correlation.
