68279-18-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 68279-18-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,2,7 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 68279-18:
(7*6)+(6*8)+(5*2)+(4*7)+(3*9)+(2*1)+(1*8)=165
165 % 10 = 5
So 68279-18-5 is a valid CAS Registry Number.

The conversion of primary amines into nitrones: an extension of the Kroehnke reaction
Katritzky, Alan R.,Dabbas, Nadira,Patel, Ranjan C.,Cozens, Andrew J.
, p. 51 - 54 (2007/10/02)
Primary amines react with 2-(ethoxycarbonyl)-4,6-diphenylpyryliums to form pyridiniums.These are hydrolysed to 2-carboxylatopyridiniums which react with p-nitroso-N,N-dimethylaniline to give nitrones.
