Check Digit Verification of cas no

The CAS Registry Mumber 19995-85-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,9 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19995-85:
(7*1)+(6*9)+(5*9)+(4*9)+(3*5)+(2*8)+(1*5)=178
178 % 10 = 8
So 19995-85-8 is a valid CAS Registry Number.

REACTIONS OF α,α-DIMETHYLALLYL ALCOHOL WITH POSITIVE CHLORINATION REAGENTS: SYNTHESIS OF 1-CHLORO-2,3-EPOXY-3-METHYLBUTANE

Bentley, Stuart,Goosen, Andre,Laue, Hugh A. H.,Taljaard, Benjamin

, p. 1566 - 1590 (2007/10/02)

Various approaches to the synthesis of the title compound, 1-chloro-2,3-epoxy-3-methylbutane, via the chlorination reactions of α,α-dimethylallyl alcohol have been followed.Attempted one-step synthesis of the epoxide from the substrate alcohol with either highly alkaline sodium hypochlorite, or t-butyl hypochlorite in the absence of solvent, gave mediocre yields of epoxide, accompanied by a variety of chlorinated products via mechanistic pathways proposed to involve neighbouring group participation (NGP) of the hydroxyl moiety.Good overall yields of epoxide were obtained in a two step synthesis involving chlorination of the alcohol with chlorine gas in solvent, followed by treatment of the chlorohydrin product with either base or dry silica gel.
