719304-25-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 719304-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,9,3,0 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 719304-25:
(8*7)+(7*1)+(6*9)+(5*3)+(4*0)+(3*4)+(2*2)+(1*5)=153
153 % 10 = 3
So 719304-25-3 is a valid CAS Registry Number.

New atropisomeric biaryl derivatives of 4-aminopyridine - Identification of an improved nucleophilic catalyst for asymmetric acylation of sec-alcohols

Spivey, Alan C.,Leese, David P.,Zhu, Fujiang,Davey, Stephen G.,Jarvest, Richard L.

, p. 4513 - 4525 (2004)

The synthesis, CSP-HPLC resolution, and absolute configuration assignment of a series of 4-dialkylaminopyridine-based atropisomeric biaryls are described. Screening of these enantiomerically pure catalysts, which differ only in the nature of the 4-dialkylamino substituent, for the kinetic resolution of 1-(1-naphthyl)ethanol reveals the importance of this group on the selectivity of catalysis. The di-n-butylamino derivative displays the most favourable catalytic profile. The utility of this catalyst for the kinetic resolution of a selection of sec-alcohols, including a precursor for the synthesis of the antidepressant fluoxetine hydrochloride (Prozac) are reported. The possible role of the dialkylamino group in chirality transfer is discussed.
