140647-18-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 140647-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,4 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 140647-18:
(8*1)+(7*4)+(6*0)+(5*6)+(4*4)+(3*7)+(2*1)+(1*8)=113
113 % 10 = 3
So 140647-18-3 is a valid CAS Registry Number.

A facile and convenient chemoenzymatic synthesis of optically active O-(4-methoxyphenyl)-glycidol and 1,2-diacyl-sn-glycerol

Kamal, Ahmed,Sandbhor, Mahendra,Shaik, Ahmad Ali,Malik, M. Shaheer

, p. 1855 - 1859 (2007/10/03)

A convenient preparation of the (R)- and (S)-enantiomers of O-(4-methoxyphenyl)-glycidol by a one-pot reduction of ketone 3 and in situ lipase mediated resolution is described. Activated moist aluminium oxide in the presence of Pseudomonas cepacia lipase immobilized on ceramic particles (PS-C) has been found effective for the transesterification leading to a high degree of enantioselectivity. These chiral glycidols were further used as a chiral precursor for the synthesis of biologically important 1,2-O-diacyl-sn-glycerol under mild reaction conditions. The present method is facile for the synthesis of chiral glycidols in high enantioselectivity when compared to the previously reported methods.
