226920-53-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 226920-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,9,2 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 226920-53:
(8*2)+(7*2)+(6*6)+(5*9)+(4*2)+(3*0)+(2*5)+(1*3)=132
132 % 10 = 2
So 226920-53-2 is a valid CAS Registry Number.

A flexible, convergent approach to piperidines, pyridines, azepines, and related derivatives
Boivin, Jean,Pothier, Julien,Zard, Samir Z.
, p. 3701 - 3704 (2007/10/03)
A highly convergent approach has been developed for the construction of various nitrogen heterocycles using as the key step the intermolecular addition of an α-ketonyl radical onto a suitably protected allylic or homoallylic amine.
