Check Digit Verification of cas no

The CAS Registry Mumber 42766-39-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,7,6 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 42766-39:
(7*4)+(6*2)+(5*7)+(4*6)+(3*6)+(2*3)+(1*9)=132
132 % 10 = 2
So 42766-39-2 is a valid CAS Registry Number.

Palladium-catalyzed decarboxylative coupling of potassium nitrophenyl acetates with aryl halides

Shang, Rui,Huang, Zheng,Chu, Ling,Fu, Yao,Liu, Lei

supporting information; experimental part, p. 4240 - 4243 (2011/10/09)

A palladium-catalyzed decarboxylative cross-coupling of potassium 2- and 4-nitrophenyl acetates with aryl chlorides and bromides has been developed. Because the nitro group can be readily converted to many other functional groups, the new reaction provides a useful method for the preparation of diverse 1,1-diaryl methanes and their derivatives.
