Check Digit Verification of cas no
The CAS Registry Mumber 229621-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,6,2 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 229621-20:
(8*2)+(7*2)+(6*9)+(5*6)+(4*2)+(3*1)+(2*2)+(1*0)=129
129 % 10 = 9
So 229621-20-9 is a valid CAS Registry Number.

Ka?lai, Tama?s,Balog, Ma?ria,Jeko?, Jo?zsef,Hideg, Ka?lma?n
, p. 973 - 980 (2007/10/03)
Symmetric paramagnetic diene 6 was prepared and proved to be a useful intermediate in 1,4-addition, cheletropic, and Diels-Alder reactions. These methods were used for the synthesis of both aromatic 10, 12 heteroaromatic 15, 23 and heterocyclic ring fused
