Check Digit Verification of cas no

The CAS Registry Mumber 808750-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,8,7,5 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 808750-49:
(8*8)+(7*0)+(6*8)+(5*7)+(4*5)+(3*0)+(2*4)+(1*9)=184
184 % 10 = 4
So 808750-49-4 is a valid CAS Registry Number.

Pd-catalyzed reactions on pyridinium N-heteroarylaminides. Step-by-step synthesis of 3,5-unsymmetrically disubstituted 2-aminopyridines

Córdoba, Marta,Castillo, Rafael R.,Izquierdo, M. Luisa,Alvarez-Builla, Julio

experimental part, p. 2624 - 2632 (2010/05/01)

Suzuki-Miyaura cross-coupling processes on N-pyridinium bromoazinyl aminides allow access to 3,5-disubstituted N-alkyl-2-aminopyridines. The synthetic pathway involves a regioselective bromination of pyridinium N-(pyridin-2-yl)aminide and a subsequent reaction with boronic acids to afford monosubstituted aminides in good yields. An additional bromination in the 5-position of the pyridine ring followed by a coupling reaction gives pyridinium N-(3,5-diarylpyridin-2-yl)aminides. Finally, a regioselective alkylation on the exo-nitrogen and reduction of the N-N bond yields highly substituted 2-aminopyridines.

, p. 1351 - 1370 (2008/09/18)

An extensive study of Suzuki-Miyaura cross-coupling processes on N-pyridinium bromoazinyl aminides has been performed. Mono- and disubstitution on 5- and 3,5-bromo derivatives produced the corresponding aryl derivatives. In the disubstituted compounds reg
