61057-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61057-05-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,0,5 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 61057-05:
(7*6)+(6*1)+(5*0)+(4*5)+(3*7)+(2*0)+(1*5)=94
94 % 10 = 4
So 61057-05-4 is a valid CAS Registry Number.

Oxidation of Secondary Amines to Nitroxides with Oxone in Aqueous Buffered Solution
Brik, M. E.
, p. 5519 - 5522 (1995)
Under biphasic conditions (CH2Cl2/H2O) using acetone, oxone, buffer and phase-transfer catalyst Bu4NHSO4-, some secondary amines without α hydrogens are oxidized to their corresponding nitroxides in rapid and good yields.
