1097637-57-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1097637-57-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,7,6,3 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1097637-57:
(9*1)+(8*0)+(7*9)+(6*7)+(5*6)+(4*3)+(3*7)+(2*5)+(1*7)=194
194 % 10 = 4
So 1097637-57-4 is a valid CAS Registry Number.

Organocatalytic approach to (s)-1-arylpropan-2-ols: Enantioselective synthesis of the key intermediate of antiepileptic agent (-)-talampanel

Sawant, Rajiv T.,Waghmode, Suresh B.

experimental part, p. 2269 - 2277 (2010/09/11)

An efficient organocatalytic route for the preparation of enantioselective synthesis of (S)-1-arylpropan-2-ols derivatives, including the key intermediate of antiepileptic agent (-)-talampanel is described. The key steps involved are L-proline-catalyzed a

First asymmetric total synthesis of novel and cytotoxic 2′-R-hydroxylanneaquinol

Suresh,Rajesh,Jon Paul Selvam,Venkateswarlu

body text, p. 7358 - 7360 (2009/05/07)

A novel cytotoxic alkylated hydroquinone 2′-R-hydroxylanneaquinol (1), isolated from the organic extract of the plant Lannea welwitschii, has been synthesized for the first time using commercially available 4-methoxyphenol. The key step of this process involves the kinetic resolution of epoxide 6 using Jacobsen's reaction conditions.
