Check Digit Verification of cas no
The CAS Registry Mumber 1198413-17-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,4,1 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1198413-17:
(9*1)+(8*1)+(7*9)+(6*8)+(5*4)+(4*1)+(3*3)+(2*1)+(1*7)=170
170 % 10 = 0
So 1198413-17-0 is a valid CAS Registry Number.

Synthesis of halogenated 4H-pyrido[1,2-a]pyrimidin-4-ones
Molnar, Annamaria,Faigl, Ferenc,Podanyi, Benjamin,Finta, Zoltan,Balazs, Laszlo,Hermecza, Istvan
experimental part, p. 2477 - 2488 (2010/04/29)
Halogenated 4H-pyrido[l,2-a]pyrimidin-4-one were synthesized by thermal cyclization and decarboxylation of isopropylidene (2-pyridylamino)methylenemalonates, prepared from 2-aminopyridines and isopropylidene methoxymethylenemalonate formed in situ. Instead of 4H-pyrido[l,2-a]pyrimidin-4-ones, the 6-chloro and 6-bromo derivatives afforded mixtures of 7-halo-l,4-dihydro-l,8-naphthyridin-4-ones and 1-(6-halo-2-pyridyl)-3-[(6-halo-2-pyridylamino)methylene]-1,2,3,4-tetrahydropyridine-2,4-diones. The latters formed from N-(2-pyridyl)iminoketenes, the common intermediates of 4H-pyrido[l,2-a]pyrimidin-4-one and l,8-naphthyridin-4-ones, via a "head-to-tail" [4+2] cycloaddition. 3-Halo-4H-pyrido[l,2-a]pyrimidin-4-ones were obtained from 4H-pyrido[1,2-a]pyrimidin-4-one with N-halosuccinimides. The structures of the new compounds were characterized by means of 1H NMR and 13C NMR examinations.
