5191-55-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5191-55-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,9 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5191-55:
(6*5)+(5*1)+(4*9)+(3*1)+(2*5)+(1*5)=89
89 % 10 = 9
So 5191-55-9 is a valid CAS Registry Number.

Reactions of 1,4-Bis(trimethylsilyl)-1,4-dihydropyridines with Carbonyl Compounds: A New Method for Regioselective Synthesis of 3-Alkylpyridines

Tsuge, Otohiko,Kanemasa, Shuji,Naritomi, Toshio,Tanaka, Junji

, p. 1497 - 1504 (2007/10/02)

A new method for the alkyl group introduction at the 3-position of pyridines is described: Reductive disilylation of pyridine, its 2-methyl, 3-methyl, and 4-methyl derivatives affords the corresponding 1,4-disilyl-1,4-dihydropyridines.Tn the presence of a catalytic amount of tetrabutylammonium fluoride, these dihydropyridines smoothly react with a variety of aldehydes and ketones to give 3-alkylpyridines.
