125638-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125638-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,6,3 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 125638-89:
(8*1)+(7*2)+(6*5)+(5*6)+(4*3)+(3*8)+(2*8)+(1*9)=143
143 % 10 = 3
So 125638-89-3 is a valid CAS Registry Number.

Enzymatic resolution of 2-hydroxy-4-phenylbutanoic acid and 2-hydroxy-4-phenylbutenoic acid
Chadha,Manohar
, p. 651 - 652 (2007/10/02)
Racemic 2-hydroxy-4-phenylbutanoic acid and 2-hydroxy-4-phenyl-butenoic acid have been resolved using a lipase. In each case, the (R)-2-hydroxy and the (S)-2-acetoxy acids were isolated with high enantiomeric excess and yield.
