53800-00-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53800-00-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,8,0 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 53800-00:
(7*5)+(6*3)+(5*8)+(4*0)+(3*0)+(2*0)+(1*0)=93
93 % 10 = 3
So 53800-00-3 is a valid CAS Registry Number.

2,4,7-Cyclooctatrien-1-one
Meier, Herbert,Lorch, Margret,Petersen, Hermann,Gugel, Hansjoerg
, p. 1418 - 1424 (2007/10/02)
The synthesis of 2,4,7-cyclooctatrien-1-one (2) is performed on the route 3 -> 7 -> 10 (-> 12) -> 2.The cross-conjugated system isomerizes thermally very smoothly to 2,4,6-cyclooctatrien-1-one (1).This process is also important for the photochemical behaviour.
