Check Digit Verification of cas no

The CAS Registry Mumber 1581291-69-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,1,2,9 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1581291-69:
(9*1)+(8*5)+(7*8)+(6*1)+(5*2)+(4*9)+(3*1)+(2*6)+(1*9)=181
181 % 10 = 1
So 1581291-69-1 is a valid CAS Registry Number.

Palladium(II)-catalyzed direct regioselectively oxidative acylation of azobenzenes with toluene derivatives

Song, Hongyu,Chen, Dong,Pi, Chao,Cui, Xiuling,Wu, Yangjie

, p. 2955 - 2962 (2014/05/06)

A highly efficient and practical procedure to acylazobenzene via Pd-catalyzed oxidative C-H bond activation from toluene has been developed. Various mono- and diacylazobenzene were afforded simultaneously in moderate to excellent yields for 33 examples. Toluene and its derivatives were served as potential and ideal acylation reagents. The mono- and diacylated products could be controlled by the oxidant loading.
