Check Digit Verification of cas no

The CAS Registry Mumber 85858-09-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,8,5 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 85858-09:
(7*8)+(6*5)+(5*8)+(4*5)+(3*8)+(2*0)+(1*9)=179
179 % 10 = 9
So 85858-09-9 is a valid CAS Registry Number.

On the Stereoselectivity of Epoxide Formation using Dimethyloxosulphonium Methylide. X-Ray Structure of (5SR)-5-pyrrolidin-2-one

Fray, M. Jonathan,Thomas, Eric J.,Wallis, John D.

, p. 395 - 402 (2007/10/02)

As background to a proposed dendrobatid toxin 251 D synthesis, the stereoselectivity of epoxide formation from 5-acetylpyrrolidin-2-one (4) and dimethyloxosulphonium methylide was investigated.In THF under 'salt-free' conditions, the major epoxide product, selectivity 78:22, was (5SR)-5-pyrrolidin-2-one (5), whereas addition of anhydrous ZnCl2 to the reaction mixture reversed the stereoselectivity to give epoxides (5) and (6) in the ratio 23:77.Configurations were assigned to these epoxides by comparison of n.m.r. spectra of the derived carbamates (15) and (16), and by an X-ray structure determination for epoxide (6).Related reactions are discussed.
