Check Digit Verification of cas no
The CAS Registry Mumber 33809-52-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,8,0 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 33809-52:
(7*3)+(6*3)+(5*8)+(4*0)+(3*9)+(2*5)+(1*2)=118
118 % 10 = 8
So 33809-52-8 is a valid CAS Registry Number.

Chemoenzymatic synthesis of chiral unsymmetrical benzoin esters
Hoyos, Pilar,Pace, Vittorio,Sinisterra, José V.,Alcántara, Andrés R.
, p. 7321 - 7329 (2011/10/09)
A chemoenzymatic Dynamic Kinetic Resolution (DKR) of unsymmetrical benzoins (Ar1≠Ar2) has been carried out, by using Pseudomonas stutzeri lipase stereorecognition pattern. After studying this lipase behaviour, a high preference towards acylation of those benzoins containing substituents in the phenyl ring rather than in the benzoyl moiety was observed. This fact allowed the development of the DKR process of this kind of substrates, avoiding the accumulation of secondary products derived from the in situ racemization mediated by Shvo's catalyst action, and allowing the synthesis of enantiopure unsymmetrical benzoins acetates (not previously described) in very good yields (60-95%) and excellent enantiomeric excess values (always >99%).
