Check Digit Verification of cas no

The CAS Registry Mumber 1373889-46-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,8,8 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1373889-46:
(9*1)+(8*3)+(7*7)+(6*3)+(5*8)+(4*8)+(3*9)+(2*4)+(1*6)=213
213 % 10 = 3
So 1373889-46-3 is a valid CAS Registry Number.

Cyanoacetamides (IV): Versatile one-pot route to 2-quinoline-3-carboxamides

Wang, Kan,Herdtweck, Eberhardt,Doemling, Alexander

experimental part, p. 316 - 322 (2012/06/18)

Cyanoacetic acid derivatives are the starting materials for a plethora of multicomponent reaction (MCR) scaffolds. Herein, we describe scope of a valuable general protocol for the synthesis of arrays of 2-aminoquinoline-3-carboxamides from cyanoacetamides and 2-aminobenzaldehydes or heterocyclic derivatives via a Friedlaender reaction variation. In many cases, the reactions involve a very convenient work up by simple precipitation and filtration. More than 40 new products are described. We foresee our protocol and the resulting derivatives becoming very valuable to greatly expanding the scaffold space of cyanoacetamide derivatives.
