Check Digit Verification of cas no
The CAS Registry Mumber 1202522-11-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,5,2 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1202522-11:
(9*1)+(8*2)+(7*0)+(6*2)+(5*5)+(4*2)+(3*2)+(2*1)+(1*1)=79
79 % 10 = 9
So 1202522-11-9 is a valid CAS Registry Number.

Three-component strategy toward 5-membered heterocycles from isocyanide dibromides.
Kaim, Laurent El,Grimaud, Laurence,Patil, Pravin
, p. 1261 - 1263 (2011/04/25)
A three-component strategy starting from isocyanides allows a straightforward synthesis of five-membered ring heterocycles. New cascades were developed involving the addition of a nitrogenated nucleophile-an azide or a tetrazole-on isocyanide dibromides,
