Check Digit Verification of cas no

The CAS Registry Mumber 147118-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,1,1 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 147118-32:
(8*1)+(7*4)+(6*7)+(5*1)+(4*1)+(3*8)+(2*3)+(1*2)=119
119 % 10 = 9
So 147118-32-9 is a valid CAS Registry Number.

Oxidative dehydrogenation of dihydropyrimidinones and dihydropyrimidines

Yamamoto, Kana,Chen, Ye Grace,Buono, Frederic G.

, p. 4673 - 4676 (2007/10/03)

(Chemical Equation Presented) A mild, practical procedure for oxidative dehydrogenation with catalytic amounts of a Cu salt, K2CO 3, and tert-butylhydroperoxide (TBHP) as a terminal oxidant has been developed. This oxidation procedure is generally applicable to dihydropyrimidinones and most dihydropyrimidines.

Synthesis and biological activity of methanesulfonamide pyrimidine- and N-methanesulfonyl pyrrole-substituted 3,5-dihydroxy-6-heptenoates, a novel series of HMG-CoA reductase inhibitors

Watanabe, Masamichi,Koike, Haruo,Ishiba, Teruyuki,Okada, Tetsuo,Seo, Shujiro,Hirai, Kentaro

, p. 437 - 444 (2007/10/03)

A novel series of methanesulfonamide pyrimidine- and N-methanesulfonyl pyrrole-substituted 3,5-dihydroxy-6-heptenoates were synthesized and evaluated for their ability to inhibit the enzyme HMG-CoA reductase in vitro. Monocalcium bis(+)-7-[4-(4-fluorophenyl)-6-isopropyl-2-(N-methyl-N- methanesulfonylaminopyrimidin)-5-yl]-(3R,5S)-dihydroxy- (E)-6-heptenoate (3a, S-4522) was selected as a candidate for further evaluation. Compound 3a was approximately four times more potent than lovastatin sodium salt (in inhibiting HMG-CoA reductase in vitro (IC50 = 11 nM). Compound 3a was shown to be the most potent cholesterol biosynthesis inhibitor in this series (IC50 = 1.12 nM) in rat isolated hepatocytes; its inhibitory activity was approximately 100 times more potent than pravastatin.
