74642-66-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74642-66-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,4 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74642-66:
(7*7)+(6*4)+(5*6)+(4*4)+(3*2)+(2*6)+(1*6)=143
143 % 10 = 3
So 74642-66-3 is a valid CAS Registry Number.

Enatioselective Microbial Reduction of Monoesters of 1,3-Dihydroxypropanone: Synthesis of (S)- and (R)-1,2-O-Isopropylideneglycerol

Aragozzini, Fabrizio,Maconi, Elisabetta,Potenza, Donatella,Scolastico, Carlo

, p. 225 - 227 (2007/10/02)

The reduction of 3-benzoyloxy-1-hydroxypropanone with bakers' yeast proceeds enantioselectively to afford (S)-3-benzoyloxy-1,2-propanediol, which may be further converted into (S)-(benzoyloxymethyl)oxirane.The bioreduction with fermenting yeast of 1-acetoxy-3-benzyloxypropanones gives (R)-1-benzyloxy-3-acetoxy-2-propanol which can be used for the preparation of both (S)- and (R)-1,2-O-isopropylideneglycerol.

A Possible Model for a New Chiral Glyceride Synthesis. Part 2. Synthesis of 1,3-Di-O-aroyl- and 1-O-Aroyl-3-O-tosyl-sn-glycerols from 2,5-O-Methylene-D-mannitol

Morpain, Claude,Fousseret-Dodane, Evelyne,Tisserand, Madeleine

, p. 1 - 6 (2007/10/02)

1,3-Di-O-aroyl- and 1-O-aroyl-3-O-tosyl-sn-glycerols have been prepared from D-mannitol via 2,5-O-methylene-D-mannitol.Some 1,3-diglycerides have also been synthesised from 3-O-aroyl-sn-glycerols.The optical rotations and the structure of the 1,3-diglycer
