Check Digit Verification of cas no

The CAS Registry Mumber 352438-07-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,2,4,3 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 352438-07:
(8*3)+(7*5)+(6*2)+(5*4)+(4*3)+(3*8)+(2*0)+(1*7)=134
134 % 10 = 4
So 352438-07-4 is a valid CAS Registry Number.

New Routes to Chiral Evans Auxiliaries by Enzymatic Desymmetrisation and Resolution Strategies

Neri, Claudia,Williams, Jonathan M. J.

, p. 835 - 848 (2007/10/03)

This paper describes how enantiomerically enriched Evans auxiliaries can be successfully prepared by either an enzymatic desymmetrisation strategy or an asymmetric synthesis using racemic auxiliaries and an enzymatic resolution. Desymmetrisation of N-Boc-protected serinol has been achieved in good yield and high enantiomeric excess using porcine pancreas lipase. This has been exploited in different ways to prepare enantiomerically enriched (4R)- and (4S)-substituted 2-oxazolidinones. In another approach to asymmetric synthesis, starting from a racemic Evans auxiliary, by means of a diastereoselective aldol reaction coupled with a lipase-catalysed resolution, we achieved the preparation of enantiomerically enriched β-hydroxy acids and enantiomerically enriched 2-oxazolidinones.
