Check Digit Verification of cas no
The CAS Registry Mumber 835873-12-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,5,8,7 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 835873-12:
(8*8)+(7*3)+(6*5)+(5*8)+(4*7)+(3*3)+(2*1)+(1*2)=196
196 % 10 = 6
So 835873-12-6 is a valid CAS Registry Number.

Radical cyclization approach to spirocyclohexadienones
Gonzalez-Lopez De Turiso, Felix,Curran, Dennis P.
, p. 151 - 154 (2007/10/03)
(Chemical Equation Presented) Cyclization of an aryl radical at the ipso position of a p-O-aryl-substituted acetamide or benzamide generates oxindoles or quinolones bearing spirocyclohexadienone rings. This versatile reaction is applied to formal synthese
