Check Digit Verification of cas no

The CAS Registry Mumber 196309-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,3,0 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 196309-63:
(8*1)+(7*9)+(6*6)+(5*3)+(4*0)+(3*9)+(2*6)+(1*3)=164
164 % 10 = 4
So 196309-63-4 is a valid CAS Registry Number.

Studies on sequential Claisen rearrangement: Charge-accelerated [3,3]-sigmatropic rearrangement leading to polyheterocycles

Majumdar,Saha,Debnath

, p. 3657 - 3665 (2008/03/13)

A number of quinolone-annulated pentacycles have been regioselectively synthesized in 90-95% yields by sequential Claisen rearrangements. The second synthesis is anhydrous AlCl3-catalyzed charge-accelerated aromatic Claisen rearrangement of 1-aryloxymethy
