Check Digit Verification of cas no

The CAS Registry Mumber 171734-48-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,7,3 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 171734-48:
(8*1)+(7*7)+(6*1)+(5*7)+(4*3)+(3*4)+(2*4)+(1*8)=138
138 % 10 = 8
So 171734-48-8 is a valid CAS Registry Number.

Enantioselective desymmetrization of prochiral ketones via an organocatalytic deprotonation process

Claraz, Aurelie,Oudeyer, Sylvain,Levacher, Vincent

, p. 764 - 768 (2013/07/25)

The first desymmetrization of 4-substituted cyclohexanones by organocatalytic asymmetric deprotonation at low catalyst loading is reported. The combination of N,O-bis(trimethylsilyl)acetamide (BSA) and chiral quaternary ammonium aryloxide salts has been u

Towards energetically viable asymmetric deprotonations: Selectivity at more elevated temperatures with C2-symmetric magnesium bisamides

Bennie, Linsey S.,Kerr, William J.,Middleditch, Michael,Watson, Allan J. B.

supporting information; experimental part, p. 2264 - 2266 (2011/04/12)

A novel chiral magnesium bisamide has enabled the development of effective asymmetric deprotonation protocols at substantially more elevated temperatures. This new, structurally simple, C2-symmetric magnesium complex displays excellent levels o

Enantioselective approaches to potential MetAP-2 reversible inhibitors

Rodeschini, Vincent,Van De Weghe, Pierre,Salomon, Emmanuel,Tarnus, Celine,Eustache, Jacques

, p. 2409 - 2412 (2007/10/03)

(Chemical Equation Presented) Enantioselective deprotonation of 4-substituted cyclohexanones and highly stereoselective conjugate addition of higher order mixed cuprates were the key steps in a concise synthesis of fumagalone-related molecules. The origin
