156546-63-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156546-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,5,4 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 156546-63:
(8*1)+(7*5)+(6*6)+(5*5)+(4*4)+(3*6)+(2*6)+(1*3)=153
153 % 10 = 3
So 156546-63-3 is a valid CAS Registry Number.

The synthesis of optically active 2-phenylthio aldehydes
Chibale, Kelly,Warren, Stuart
, p. 3991 - 3994 (2007/10/02)
Optically active linear and branched chain 2-phenylthio aldehydes can be made in high optical purity (up to > 98% e.e.) by sulfenylation of a phenylalanine-derivative oxazolidinone imide, reduction and re-oxidation with the Dess-Martin reagent even though the products enolise easily.
