Check Digit Verification of cas no

The CAS Registry Mumber 70200-72-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,0 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 70200-72:
(7*7)+(6*0)+(5*2)+(4*0)+(3*0)+(2*7)+(1*2)=75
75 % 10 = 5
So 70200-72-5 is a valid CAS Registry Number.

Direct Conversion of Arylamines to the Halides by Deamination with Thionitrite or Related Compounds and Anhydrous Copper(II) Halides

Oae, Shigeru,Shinhama, Koichi,Kim, Yong Hae

, p. 1065 - 1069 (2007/10/02)

Reactions of various arylamines with either t-butyl thionitrite, t-butyl thionitrate, or p-toluenesulfonyl nitrite in the presence of anhydrous copper(II) halides under mild conditions gave corresponding aryl halides in good yields.This reaction in the presence of such olefins as acrylonitrile, styrene, and acrylic acid gave the corresponding 2-aryl-1-haloethanes as the main products. t-Butyl thionitrite, t-butyl thionitrate, and p-toluenesulfonyl nitrite were found to be better deaminative reagents than alkyl nitrites or alkyl nitrates due to their weak sulfur-nitrogen bonds.
