Check Digit Verification of cas no

The CAS Registry Mumber 5381-89-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,8 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5381-89:
(6*5)+(5*3)+(4*8)+(3*1)+(2*8)+(1*9)=105
105 % 10 = 5
So 5381-89-5 is a valid CAS Registry Number.

Hydrogen peroxide-or sodium hypochlorite-induced bromination of 1-arylbut-2-enes

Sadygov,Alimardanov

, p. 1661 - 1670 (2008/09/18)

Bromination of 1-arylbut-2-enes in the system [HBr or NaBr (KBr)-HX]-H 2O2 (or NaOCl) under relatively mild conditions leads to electrophilic addition of bromine or hypobromous acid at the side-chain double bond. Under more severe conditions, the process is accompanied by bromination of the aromatic ring. Treatment of the title compounds with peroxy acids (RCOOH-H2O2) gives the corresponding epoxy derivatives which react with HBr and oxygen-containing nucleophiles to produce α-bromo alcohols, diols, and diol acetates.
