Check Digit Verification of cas no

The CAS Registry Mumber 374716-65-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,4,7,1 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 374716-65:
(8*3)+(7*7)+(6*4)+(5*7)+(4*1)+(3*6)+(2*6)+(1*5)=171
171 % 10 = 1
So 374716-65-1 is a valid CAS Registry Number.

Chemoenzymatic asymmetric total synthesis of nonanolide (Z)-cytospolides D, E and their stereoisomers

Rej, Rohan Kalyan,Nanda, Samik

, p. 860 - 871 (2014/03/21)

Chemoenzymatic asymmetric total synthesis of the (Z)-isomer of the naturally occurring decanolide cytospolides D, E and six stereoisomers is reported. The main highlight of the synthetic venture involves ring-closing metathesis (RCM) reaction of a suitably functionalized ester compound, which was assembled by the Yamaguchi coupling of the required acid and alcohol fragments. The alcohol fragment was ac- cessed by two alternative chemoenzymatic processes, one being hydroxynitrile lyase mediated hydrocyanation, whereas lipase-catalyzed transesterification was the key sep in the second route. The acid fragment was constructed by an enantioselective enzymatic desymmetrization (EED) of prochiral 2-methyl-1,3-propanediol and Corey-Bakshi-Shibata (CBS) mediated stereoselective carbonyl reduction.

Chemoenzymatic Approach toward the Pure Enantiomers of 2-Methyl-1,3-propanediol Mono(p-Methoxybenzyl Ether)

Akeboshi, Tomohiro,Ohtsuka, Yoshikazu,Ishihara, Takashi,Sugai, Takeshi

, p. 624 - 637 (2007/10/03)

In a route towards the enantiomerically pure 2-methylpropane-1,3-diol mono(p-methoxybenzyl ether), which is an important starting material for natural product synthesis, a kinetic resolution approach by means of lipase-catalyzed hydrolysis as well as acyl
