139034-04-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139034-04-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,3 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139034-04:
(8*1)+(7*3)+(6*9)+(5*0)+(4*3)+(3*4)+(2*0)+(1*4)=111
111 % 10 = 1
So 139034-04-1 is a valid CAS Registry Number.

Catalytic epoxidation with molecular oxygen using nickel complex
Irie, Ryo,Ito, Yoshio,Katsuki, Tsutomu
, p. 6891 - 6894 (2007/10/02)
Ni complex, [N,N′-bis[o-p-toluenesulfonylamino)benzylidene]ethylenediaminato] nickel(II) (1), was found to be a good catalyst for the epoxidation of olefins with molecular oxygen in the presence of 2-methylpropanal (Mukaiyama's conditions).
