Check Digit Verification of cas no

The CAS Registry Mumber 514806-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,4,8,0 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 514806-50:
(8*5)+(7*1)+(6*4)+(5*8)+(4*0)+(3*6)+(2*5)+(1*0)=139
139 % 10 = 9
So 514806-50-9 is a valid CAS Registry Number.

New applications of the imine-ketenimine intramolecular [2+2] cycloaddition reaction: Highly stereocontrolled synthesis of azeto[1,2-a]pyrimidines

Alajarin, Mateo,Vidal, Angel,Orenes, Raul-Angel

, p. 4222 - 4227 (2002)

Imino-ketenimines 7, in which the reactive functionalities are linked by an allylic tether connecting the imino and ketenimino nitrogen atoms, undergo a formal intramolecular [2+2] cycloaddition to yield azeto[1,2-a]pyrimidines 8. When enantiotopic ketenimine and imine fragments are combined, the resulting azeto[1,2-a]pyrimidines 8e-i contain two stereogenic carbon atoms C-6 and C-7, and the cycloaddition takes place with complete diastereoselectivity in favor of the cis diastereoisomers. This methodology has also been applied to the preparation of some azeto[1,2-a][1,3]thiazolo[4,5-d]pyrimidines 16, representative examples of a new fused heterocyclic system.
