Check Digit Verification of cas no

The CAS Registry Mumber 1262446-41-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,4,4 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1262446-41:
(9*1)+(8*2)+(7*6)+(6*2)+(5*4)+(4*4)+(3*6)+(2*4)+(1*1)=142
142 % 10 = 2
So 1262446-41-2 is a valid CAS Registry Number.

Synthesis of nitrogen bicyclic scaffolds: Pyrimido[1,2-a]pyrimidine-2,6- diones

Grosjean, Sylvain,Triki, Smail,Meslin, Jean-Claude,Julienne, Karine,Deniaud, David

experimental part, p. 9912 - 9924 (2011/02/22)

The multi-step synthesis of 1,3,7-trisubstituted pyrimido[1,2-a] pyrimidinediones starting from isothiocyanates is described. These nitrogen bicycles were prepared by an iterative sequence of functionalization/ cyclocondensation reactions. [4+2] Cycloaddition reactions took place between diazadienic chains and various acyl chlorides providing sophisticated heterobicycles.
