109191-80-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109191-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,1,9 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109191-80:
(8*1)+(7*0)+(6*9)+(5*1)+(4*9)+(3*1)+(2*8)+(1*0)=122
122 % 10 = 2
So 109191-80-2 is a valid CAS Registry Number.

Cross-Coupling Reaction of Chloropyrazines with Acetylenes
Akita, Yasuo,Inoue, Akira,Ohta, Akihiro
, p. 1447 - 1458 (2007/10/02)
Various chloropyrazines were subjected to cross-coupling reaction with acetylenes, such as phenylacetylene, 1-hexyne and propargyl alcohol, in the presence of palladium catalysts, to give the corresponding coupling products in good yields.It was found, th
