229184-04-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 229184-04-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,1,8 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 229184-04:
(8*2)+(7*2)+(6*9)+(5*1)+(4*8)+(3*4)+(2*0)+(1*4)=137
137 % 10 = 7
So 229184-04-7 is a valid CAS Registry Number.

Synthesis of tricyclic pyridones by radical cyclization
Nadin, Alan,Harrison, Timothy
, p. 4073 - 4076 (2007/10/03)
A general and novel route for the synthesis of tricyclic pyridones by 5- , 6- and 7-exo-trig radical cyclization is described. The use of Pd-catalyzed cross-coupling reactions to introduce functionality at the 5-position of a pyridone is also presented.
