Check Digit Verification of cas no

The CAS Registry Mumber 47518-92-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,7,5,1 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 47518-92:
(7*4)+(6*7)+(5*5)+(4*1)+(3*8)+(2*9)+(1*2)=143
143 % 10 = 3
So 47518-92-3 is a valid CAS Registry Number.

Synthesis of nitrogen-containing heterocyclic compounds using perfluoro-2-methylpent-2-ene and perfluoro-5-azanon-4-ene

Chi, Ki-Whan,Furin, Georgii G.,Gatilov, Yurii V.,Bagryanskay, Irina Yu.,Zhuzhgov, Eduard L.

, p. 105 - 115 (2007/10/03)

Reactions of perfluoro-2-methylpent-2-ena or perfluoro-5-azanon-4-ene with a range of bidentate nitrogen nucleophiles (urea, acet-, benz-, 4-nitrobenz-amidine hydrochloride, 2-aminopyridine, 2-aminobenzimidazole, guanidine) in the presence of Et3N or KOH effectively provided partially fluorinated heterocycles of pyrimidine, 2H-pyrido[1,2-a]pyrimidine and [1,3,5]triazine derivatives. The structure of 2-pentafluoroethyl-3-trifluoromethyl-pyrido[1,2-a]pyrimidin-4-one was further confirmed by the X-ray crystallographic analysis.
