Check Digit Verification of cas no

The CAS Registry Mumber 132331-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,3,3 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 132331-08:
(8*1)+(7*3)+(6*2)+(5*3)+(4*3)+(3*1)+(2*0)+(1*8)=79
79 % 10 = 9
So 132331-08-9 is a valid CAS Registry Number.

Regioselective, photochemical bromination of aromatic compounds using N-bromosuccinimide

Chhattise, Prakash K.,Ramaswamy,Waghmode, Suresh B.

, p. 189 - 194 (2008/03/30)

Regioselective nuclear bromination of aromatic compounds is investigated with N-bromosuccinimide as the brominating agent under UV irradiation to afford the corresponding brominated compounds. The reaction proceeds at ambient temperature (30 ± 2 °C) without any catalyst. In most of the reactions, regioselectively mono-brominated products are obtained in good to high yields. The conversion and selectivity for bromination depend on the nature of the substituent on the aromatic ring.
