Check Digit Verification of cas no

The CAS Registry Mumber 2657-51-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,5 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2657-51:
(6*2)+(5*6)+(4*5)+(3*7)+(2*5)+(1*1)=94
94 % 10 = 4
So 2657-51-4 is a valid CAS Registry Number.

Efficient halogenation of aromatic systems using N-halosuccinimides in ionic liquids

Yadav,Reddy,Reddy,Basak,Narsaiah

, p. 77 - 82 (2004)

A simple, rapid and highly regioselective green protocol has been developed for the halogenation of aromatic systems with N-halosuccinimides using room temperature ionic liquids (ILs) as novel and recyclable reaction media to produce the corresponding halogenated aromatic compounds in high to quantitative yields. N-Halosuccinimides show enhanced reactivity in ionic liquids thereby reducing the reaction times dramatically and improving the yields substantially.
