Check Digit Verification of cas no

The CAS Registry Mumber 41116-22-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,1,1 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 41116-22:
(7*4)+(6*1)+(5*1)+(4*1)+(3*6)+(2*2)+(1*2)=67
67 % 10 = 7
So 41116-22-7 is a valid CAS Registry Number.

Copper-catalyzed synthesis of primary arylamines from aryl halides and 2,2,2-trifluoroacetamide

Tao, Chuan-Zhou,Li, Juan,Fu, Yao,Liu, Lei,Guo, Qing-Xiang

, p. 70 - 75 (2008)

A catalytic method was developed to synthesize primary arylamines from the corresponding aryl bromides and iodides under mild conditions (yields = 80-99%). Crystalline 2,2,2-trifluoroacetamide was used as ammonia surrogate and CuI/N,N′-dimethyl ethylenediamine was used as catalyst to achieve the C-N cross-coupling.
