1307725-48-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1307725-48-9 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, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1307725-48:
(9*1)+(8*3)+(7*0)+(6*7)+(5*7)+(4*2)+(3*5)+(2*4)+(1*8)=149
149 % 10 = 9
So 1307725-48-9 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.
