Check Digit Verification of cas no

The CAS Registry Mumber 1416854-28-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,6,8,5 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1416854-28:
(9*1)+(8*4)+(7*1)+(6*6)+(5*8)+(4*5)+(3*4)+(2*2)+(1*8)=168
168 % 10 = 8
So 1416854-28-8 is a valid CAS Registry Number.

Competitive condensation and tandem cyclization reactions of 2-cyano-3-ferrocenylacrylonitrile with amidines in an aqueous medium

Klimova, Elena I.,Flores-Alamo, Marcos,Stivalet, Jose M. Mendez,Klimova, Tatiana

, p. 2505 - 2514 (2012)

The synthesis of a series of ferrocenyl-substituted 2-aminopyridineand 6-amino-4,5-dihydropyridine-3,5-dicarbonitriles, 4-aminopyrimidine- and 3,4-dihydropyrimidine-5-carbonitriles by reactions of 2-cyano-3- ferrocenylacrylonitrile with amidines in aqueous medium is described. New fused 6-amino-2-ethoxy-4-ferrocenyl-5-ferrocenylmethyl-5-ferrocenyl methyl-4,5- dihydropyridine-3,5-dicarbonitrile was prepared in a tricomponent cyclodimerization from 2-cyano-3-ferrocenylacrylonitrile in presence of ethanol. The structures of the obtained compounds were established by IR, 1H and 13C NMR spectroscopy, mass-spectrometry and X-ray diffraction analysis.
