Check Digit Verification of cas no

The CAS Registry Mumber 143815-75-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,1 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 143815-75:
(8*1)+(7*4)+(6*3)+(5*8)+(4*1)+(3*5)+(2*7)+(1*5)=132
132 % 10 = 2
So 143815-75-2 is a valid CAS Registry Number.

Synthesis of new heterotricyclic compounds containing the [1,8]naphthyridine group by thermal isomerization of 2-dialkylamino-3-vinylpyridines

Ojea,Peinador,Quintela

, p. 798 - 802 (2007/10/02)

2-N,N-Dialkylamino-3-(2,2-dicyanovinyl)pyridines react thermally in polar solvents via [1,5] hydrogen transfer followed by carbon-carbon bond formation to yield heterotricyclic compounds containing the [1,8]naphthyridine group. The reaction time is marked
