Check Digit Verification of cas no

The CAS Registry Mumber 313644-65-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,3,6,4 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 313644-65:
(8*3)+(7*1)+(6*3)+(5*6)+(4*4)+(3*4)+(2*6)+(1*5)=124
124 % 10 = 4
So 313644-65-4 is a valid CAS Registry Number.

Yadav, Jhillu Singh,Mishra, Anand Kumar,Dachavaram, Soma Shekar,Ganesh Kumar,Das, Saibal

, p. 2921 - 2923 (2014/05/06)

A convergent enantioselective synthesis of penicimarin B, aspergillumarin A and B has been reported using Brown's allylation, DeBrabander-Bhattacharjee lactonization and Grubbs cross coupling metathesis. During this synthesis we have standardized the conditions for DeBrabande-Bhattacharjee lactonization to obtain excellent yield (>90%).
