Check Digit Verification of cas no

The CAS Registry Mumber 4207-56-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,0 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4207-56:
(6*4)+(5*2)+(4*0)+(3*7)+(2*5)+(1*6)=71
71 % 10 = 1
So 4207-56-1 is a valid CAS Registry Number.

A simple and efficient bromoazidation of alkenes using PTT and TMSN 3 in ionic liquid

Kumar, Anil,Sudershan Rao,Mehta, Vibhor

body text, p. 1123 - 1127 (2011/10/02)

A simple and efficient one-pot method has been described for the bromoazidation of alkenes using phenyltrimethylammonium tribromide (PTT) and TMSN3 in ionic liquid. The bromoazides have been obtained in good to excellent yield from various alkenes such as styrenes, chalcones, and cycloalkenes at room temperature.
