54459-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54459-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,4,5 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 54459-03:
(7*5)+(6*4)+(5*4)+(4*5)+(3*9)+(2*0)+(1*3)=129
129 % 10 = 9
So 54459-03-9 is a valid CAS Registry Number.

Investigations on the question of multiple mechanisms in the cope rearrangement
Wigfield,Feiner,Malbacho,Taymaz
, p. 2949 - 2959 (2007/10/12)
The possible occurrence of the ionic Cope rearrangement, and other non-concerted mechanisms is discussed. The synthesis of 2 - (1 - ethyl - 1 - propenyl) -2- (3 - p - methoxyphenylallyl)malononitrile (1b) and its clean thermal 1,3 rearrangement to (1 - et
