109192-13-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109192-13-4 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 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109192-13:
(8*1)+(7*0)+(6*9)+(5*1)+(4*9)+(3*2)+(2*1)+(1*3)=114
114 % 10 = 4
So 109192-13-4 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
