General Description
3,5-Difluoromandelic acid is also known as α-hydroxy-3,5-difluorophenylacetic acid. Racemic 3,5-difluoromandelic acid undergoes optical resolution in the presence of (1R,2R)-(-)-pseudoephedrine in isopropanol to afford (S)-form.
Check Digit Verification of cas no
The CAS Registry Mumber 132741-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,7,4 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 132741-31:
(8*1)+(7*3)+(6*2)+(5*7)+(4*4)+(3*1)+(2*3)+(1*1)=102
102 % 10 = 2
So 132741-31-2 is a valid CAS Registry Number.

Kinetic resolution of mandelate esters via stereoselective acylation catalyzed by lipase PS-30
Chen, Peiran,Yang, Wenhong
, p. 2290 - 2294 (2014/04/17)
By using lipase PS-30 as catalyst, the kinetic resolution of a series of racemic mandelate esters has been achieved via stereoselective acylation. The value of kinetic enantiomeric ratio (E) reached up to 197.5. Substituent effect is briefly discussed.
