108940-99-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 108940-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,9,4 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 108940-99:
(8*1)+(7*0)+(6*8)+(5*9)+(4*4)+(3*0)+(2*9)+(1*9)=144
144 % 10 = 4
So 108940-99-4 is a valid CAS Registry Number.

Optical Resolution and Chiral Synthesis of Methyl 6,7-Dichloro-2,3-dihydrobenzofuran-2-carboxylate

Yodo, Mitsuaki,Matsushita, Yoshihiro,Ohsugi, Eiichi,Harada, Hiroshi

, p. 902 - 913 (2007/10/02)

Optical isomers of methyl 6,7-dichloro-2,3-dibenzofuran-2-carboxylate (2) were prepared by means of both optical resolution and chiral synthesis.The resolution of the carboxylic acid 3 was achieved in a practical and efficient way via the l- and d-menthyl esters, which were directly converted to enantiomers of 2.Chiral synthesis of 2 was attained with high optical yield via acid-catalyzed cyclization of the β-hydroxysulfide 10 derived from optically active glycidyl phenyl sulfide 13.The optical resolution method was considered to be better for large-scale preparation from the economical and operational viewpoints.Keywords - methyl 6,7-dichloro-2,3-dibenzofuran-2-carboxylate; optical resolution; (R)-4-phenyl-2-oxazolidone; menthol; chiral synthesis; glycidyl phenyl sulfide; β-hydroxysulfide; episulfonium ion; S-8666
