1307725-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1307725-50-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,7,7,2 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1307725-50:
(9*1)+(8*3)+(7*0)+(6*7)+(5*7)+(4*2)+(3*5)+(2*5)+(1*0)=143
143 % 10 = 3
So 1307725-50-3 is a valid CAS Registry Number.

Iron-catalyzed cycloaddition of alkynenitriles and alkynes
Dsouza, Brendan R.,Lane, Timothy K.,Louie, Janis
supporting information; experimental part, p. 2936 - 2939 (2011/07/09)
The combination of Fe(OAc)2 and an electron-donating, sterically hindered pyridyl bisimine ligand catalyzes the cycloaddition of alkynenitriles and alkynes. A variety of substituted pyridines were obtained in good yields.
