Check Digit Verification of cas no

The CAS Registry Mumber 1620217-65-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,2,1 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1620217-65:
(9*1)+(8*6)+(7*2)+(6*0)+(5*2)+(4*1)+(3*7)+(2*6)+(1*5)=123
123 % 10 = 3
So 1620217-65-3 is a valid CAS Registry Number.

, p. 4458 - 4462 (2014/08/05)

Under open-flask conditions, an efficient method to assemble a series of diversely functionalized diarylketones in the presence of commercially available NBS has been developed. Yields of up to 99% have been achieved employing diarylmethanes as starting material. Based on 18O-labeled experiment, the addition of stoichiometric water eventually leads to excellent yields in all carbonylation cases.
