Check Digit Verification of cas no
The CAS Registry Mumber 129760-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,6 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129760-33:
(8*1)+(7*2)+(6*9)+(5*7)+(4*6)+(3*0)+(2*3)+(1*3)=144
144 % 10 = 4
So 129760-33-4 is a valid CAS Registry Number.

Shen, Yanchang,Xiang, Yuejun
, p. 2493 - 2494 (2007/10/02)
4-Trifluoromethyl-2,4-dienamides can be successfully synthesized by the reaction of trifluoromethylated arsoranes, generated from the transylidation between fluorinated β-oxoalkylphosphonium salts and methylenetriphenylarsorane, with α-bromoacetamides.
