89637-67-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89637-67-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,3 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89637-67:
(7*8)+(6*9)+(5*6)+(4*3)+(3*7)+(2*6)+(1*7)=192
192 % 10 = 2
So 89637-67-2 is a valid CAS Registry Number.

Catalytic epoxidation with molecular oxygen using nickel complex
Irie, Ryo,Ito, Yoshio,Katsuki, Tsutomu
, p. 6891 - 6894 (1991)
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).
