Check Digit Verification of cas no

The CAS Registry Mumber 475292-59-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,5,2,9 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 475292-59:
(8*4)+(7*7)+(6*5)+(5*2)+(4*9)+(3*2)+(2*5)+(1*9)=182
182 % 10 = 2
So 475292-59-2 is a valid CAS Registry Number.

Synthesis of 3,4-disubstituted piperidines by carbonyl ene and prins cyclizations: Switching between kinetic and thermodynamic control with Bronsted and Lewis acid catalysts

Williams, Jodi T.,Bahia, Perdip S.,Kariuki, Benson M.,Spencer, Neil,Philp, Douglas,Snaith, John S.

, p. 2460 - 2471 (2007/10/03)

A novel approach to cis and trans 3,4-disubstituted piperidines is described. Carbonyl ene cyclization of aldehydes 4a-e catalyzed by MeAlCl 2 in refluxing chloroform afforded the trans piperidines 7a-e with diastereomeric ratios of up to 93:7,

Synthesis of 3-Substituted 4-Piperidinones via a One-Pot Tandem Oxidation-Cyclization-Oxidation Process: Stereodivergent Reduction to 3,4-Disubstituted Piperidines

Bahia, Perdip S.,Snaith, John S.

, p. 3226 - 3229 (2007/10/03)

A novel approach to 3-substituted 4-piperidinones is described. The one-pot tandem oxidation-cyclization-oxidation of unsaturated alcohols 1a-e by PCC or PCC and trifluoromethanesulfonic acid affords piperidinones 2a-e in good yield. Reduction of 2a-e by

Synthesis of 3,4-disubstituted piperidines by carbonyl Ene and Prins cyclizations: A switch in diastereoselectivity between Lewis and Bronsted acid catalysts

Williams, Jodi T.,Bahia, Perdip Singh,Snaith, John S.

, p. 3727 - 3730 (2007/10/03)

(graph presented) A novel diastereoselective approach to cis and trans 3,4-disubstituted piperidines is described. Carbonyl ene cyclization of aldehydes 6a-e catalyzed by the Lewis acid methyl aluminum dichloride in refluxing chloroform affords trans piperidines 8a-e with diastereomeric ratios of up to 93:7. By contrast, Prins cyclization of 6a-e catalyzed by hydrochloric acid at low temperatures affords cis products 7a-e with diastereomeric ratios of up to 98:2.
