Check Digit Verification of cas no

The CAS Registry Mumber 121641-63-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,4 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121641-63:
(8*1)+(7*2)+(6*1)+(5*6)+(4*4)+(3*1)+(2*6)+(1*3)=92
92 % 10 = 2
So 121641-63-2 is a valid CAS Registry Number.

, p. 1831 - 1835 (2007/10/02)

Lewis acid catalyzed cycloaddition reactions of ethylglyoxylate imines to dihydrofuran and indene yield substituted hexahydrofuro- and tetrahydro-7H-indenoquinolines respectively.Oxidation of the adducts with 2,3-dichloro-5,6-dicyanobenzoquinone affords the corresponding aromatic compounds.
