Check Digit Verification of cas no

The CAS Registry Mumber 914646-14-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,4,6,4 and 6 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 914646-14:
(8*9)+(7*1)+(6*4)+(5*6)+(4*4)+(3*6)+(2*1)+(1*4)=173
173 % 10 = 3
So 914646-14-3 is a valid CAS Registry Number.

A short enantioselective synthesis of (-)-chloramphenicol and (+)-thiamphenicol using tethered aminohydroxylation

George, Shyla,Narina, Srinivasarao V.,Sudalai, Arumugam

, p. 10202 - 10207 (2007/10/03)

An efficient enantioselective synthesis of (-)-chloramphenicol (1) and (+)-thiamphenicol (2) is described. These antibiotics have been synthesized from commercially available 4-nitrobenzaldehyde and 4-(methylthio)benzaldehyde, respectively, using tethered aminohydroxylation and Sharpless asymmetric epoxidation as the chirality inducing steps.
