Check Digit Verification of cas no

The CAS Registry Mumber 80082-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,0,8 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 80082-18:
(7*8)+(6*0)+(5*0)+(4*8)+(3*2)+(2*1)+(1*8)=104
104 % 10 = 4
So 80082-18-4 is a valid CAS Registry Number.

Pyrimidopyridazines. 5. Summary of Cyclizations with Vicinally Functionalized Reagents and Studies of the Reductive Behavior of the Ring System

Morrison, Robert W.,Styles, Virgil L.

, p. 674 - 680 (2007/10/02)

New syntheses of pyrimidopyridazines from 6-hydrazinoisocytosines and vicinal carbonyl reagents and reduction studies with selected members of this compound series are reported.Structural features required for pyrimidopyridazine formation from reactions of 2-amino-4-hydrazinopyrimidines with vicinal difunctional reagents and selectivity with respect to product substituent orientations are summarized.
