Check Digit Verification of cas no

The CAS Registry Mumber 110823-92-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,8,2 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 110823-92:
(8*1)+(7*1)+(6*0)+(5*8)+(4*2)+(3*3)+(2*9)+(1*2)=92
92 % 10 = 2

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.
