Check Digit Verification of cas no

The CAS Registry Mumber 1413431-91-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,3,4,3 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1413431-91:
(9*1)+(8*4)+(7*1)+(6*3)+(5*4)+(4*3)+(3*1)+(2*9)+(1*1)=120
120 % 10 = 0
So 1413431-91-0 is a valid CAS Registry Number.

Regioselective synthesis of 7,8-dihydroimidazo [5,1-c][1,2,4]triazine-3, 6(2H,4H)-dione derivatives: A new drug-like heterocyclic scaffold

Tzvetkov, Nikolay T.,Euler, Harald,Mueller, Christa E.

, p. 1584 - 1593 (2012/11/07)

Dihydroimidazo[5,1-c][1,2,4]triazine-3,6(2H,4H)-dione derivatives were prepared by successive N3- and N1-alkylation of hydantoins, followed by regioselective thionation and subsequent cyclization under mild conditions. In a final alkylation step a further substituent may be introduced. The synthetic strategy allows broad structural variation of this new drug-like heterobicyclic scaffold. In addition to extensive NMR and MS analyses, the structure of one derivative was confirmed by X-ray crystallography.
