Check Digit Verification of cas no

The CAS Registry Mumber 1111072-24-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,1,0,7 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1111072-24:
(9*1)+(8*1)+(7*1)+(6*1)+(5*0)+(4*7)+(3*2)+(2*2)+(1*4)=72
72 % 10 = 2
So 1111072-24-2 is a valid CAS Registry Number.

Regio- and stereo-specific preparation of (E)-1-aryl-3,3,3-trifluoro-1-iodo-propenes and their palladium-catalyzed reaction with terminal alkynes

Zhang, Xing-Guo,Chen, Mu-Wang,Zhong, Ping,Hu, Mao-Lin

, p. 335 - 342 (2008/12/22)

A new type of iodo-containing trifluoromethylated building blocks were synthesized. The reaction of 1-aryl-3,3,3-trifluoropropynes 1 with lithium iodide in acetic acid at 75 °C gave (E)-1-aryl-3,3,3-trifluoro-1-iodo-propenes 2 in high yield, which undergo the palladium-catalyzed Sonogashira reaction with terminal alkynes afforded trifluoromethyl-containing 1,3-enynes in high yield.
