478550-42-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 478550-42-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,8,5,5 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 478550-42:
(8*4)+(7*7)+(6*8)+(5*5)+(4*5)+(3*0)+(2*4)+(1*2)=184
184 % 10 = 4
So 478550-42-4 is a valid CAS Registry Number.

New bichromophoric-2,2′-bipyridines: synthesis and optical properties

Lohio, Olivier,Viau, Lydie,Maury, Olivier,Bozec, Hubert Le

, p. 1229 - 1232 (2007)

The synthesis and characterization of new unsymmetrically substituted bipyridyl-based chromophores featuring π-conjugated donor, acceptor or photoisomerizable backbones are reported. Their absorption and emission properties are discussed in comparison to

Synthesis and characterization of 4-alkenyl and 4,4′-dialkenyl-2,2′-bipyridyl ligands bearing π-donor substituents

Bourgault,Renouard,Lognone,Mountassir,Le Bozec

, p. 318 - 325 (2007/10/03)

The synthesis of a new series of π-donor mono- and disubstituted vinyl bipyridines (donor = 4-R2N-C6H4-; 4-RO-C6H4-; (C5H5)Fe(C5H4-); (C5H5)Ru(C5H4-)) has been achieved by reaction of the mono- and dilithio species of 4,4′-dimethyl-2,2′-bipyridine and the monolithio species of 4-nonyl-4′-methyl-2,2′-bipyridine with the appropriate aldehydes. Their 1H NMR and UV-visible characterizations are reported.
