17431-41-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17431-41-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,4,3 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17431-41:
(7*1)+(6*7)+(5*4)+(4*3)+(3*1)+(2*4)+(1*1)=93
93 % 10 = 3
So 17431-41-3 is a valid CAS Registry Number.

Diastereoselective darzens condensations of α-haloamides: Influence of aryl substituents on diastereoselectivity

North, Michael,Pizzato, Francesca

experimental part, p. 552 - 556 (2010/04/23)

N, N-Diaryl α-haloamides undergo Darzens condensations with aldehydes induced by metal hydroxides. The diastereoselectivity of epoxide formation is strongly influenced by the electronic properties of the arylamide, which can be rationalised on the basis of the acidity of the substrate hydrogens and hence on reaction occurring under kinetic or thermodynamic control.
