Check Digit Verification of cas no

The CAS Registry Mumber 74642-90-3 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, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74642-90:
(7*7)+(6*4)+(5*6)+(4*4)+(3*2)+(2*9)+(1*0)=143
143 % 10 = 3
So 74642-90-3 is a valid CAS Registry Number.

Resolution of trans-1,2-Dihydroxy-1,2-dihydrobenzene for the Preparation of Optically Pure Benzene Diol Epoxides. Preparation of Bromo- and Chlorobenzene Diol Epoxides

Ganey, Michael V.,Padykula, Robert E.,Berchtold, Glenn A.,Braun, Andrew G.

, p. 2787 - 2793 (1989)

The resolution of (+/-)-trans-1,2-dihydroxy-1,2-dihydrobenzene has been accomplished by esterase-catalysed hydrolysis of diacetate (+/-)-5.Peracid epoxidation of (+)-2 and (-)-2 gave diol epoxides (+)-3 and (-)-3, respectively.The synthesis of d

Enantiospecific and Stereoselective Synthesis of (-)-Conduritol C from Chlorobenzene via Microbial Oxidation and Epoxidation

Carless, Howard A. J.

, p. 234 - 235 (2007/10/02)

A four-step route to (-)-conduritol C 1 is described, via the enantiospecific conversion of chlorobenzene to the diene cis-diol 7 and subsequent cis-epoxidation to yield 8.
