110930-71-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 110930-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,9,3 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 110930-71:
(8*1)+(7*1)+(6*0)+(5*9)+(4*3)+(3*0)+(2*7)+(1*1)=87
87 % 10 = 7
So 110930-71-7 is a valid CAS Registry Number.

Lipase-catalyzed resolution of esters of 4-chloro-3-hydroxybutanoic acid: Effects of the alkoxy group and solvent on the enantiomeric ratio

Hoff, Bard Helge,Anthonsen, Thorleif

, p. 1401 - 1412 (2007/10/03)

Various lipases have been investigated for their potential use as catalysts for the resolution of esters of 4-chloro-3-hydroxybutanoic acid via transesterification in organic solvents. Rhizomucor miehei lipase was found to be the most efficient lipase, with the enantiomeric ratio (E) being dependent upon of the nature of the alkoxy group of the ester and the resolution medium. Higher E-values were obtained when transesterification was performed in benzene or carbon tetrachloride than was the case in hexane. In mixtures of benzene and hexane the trend in E-values followed a linear relationship.
