The CAS Registry Mumber 25650-58-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,6,5 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 25650-58:
(7*2)+(6*5)+(5*6)+(4*5)+(3*0)+(2*5)+(1*8)=112
112 % 10 = 2
So 25650-58-2 is a valid CAS Registry Number.

ELECTRON-TRANSFER ACTIVATION. SALT EFFECTS ON THE PHOTOOXADIDATION OF TERTIARY AMINES : A USEFUL N-DEMETHYLATION METHOD

Santamaria, J.,Ouchabane, R.,Rigaudy, J.

, p. 3977 - 3980 (2007/10/02)

Photooxidation of tertiary methylamines sensitized by electron acceptors like 9,10-dicyanoanthracene is shown to proceed by two distinct ways depending on the presence of added salts.In the absence of added salt both nor and N-formyl compounds were obtained while with added salt the nor-derivative is obtained highly efficiently.
