21567-23-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21567-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,6 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21567-23:
(7*2)+(6*1)+(5*5)+(4*6)+(3*7)+(2*2)+(1*3)=97
97 % 10 = 7
So 21567-23-7 is a valid CAS Registry Number.

New aspects of catalytic intramolecular C-H amination: Unexpected formation of a seven-membered ring in nitrogen-containing systems

Toumieux, Sylvestre,Compain, Philippe,Martin, Olivier R.,Selkti, Mohamed

, p. 4493 - 4496 (2006)

The first example of the formation of a seven-membered ring by way of intramolecular-catalyzed amination of saturated C-H bonds is reported (Du Bois reaction). The influence of various structural parameters was studied, and it was shown that the unexpected regioselectivity observed in nitrogen-containing systems could be rationalized by conformational factors. These results open the way to innovative strategies for the general synthesis of polyfunctionalized piperidines.
