1,2-Cycloundecanedione is a cyclic ketone with the molecular formula C11H18O2. It is a colorless to pale yellow crystalline solid that is soluble in organic solvents. 1,2-Cycloundecanedione is characterized by its unique 11-membered ring structure, which includes two carbonyl groups (C=O) at the 1 and 2 positions. 1,2-Cycloundecanedione is synthesized through various chemical reactions, such as the oxidation of cycloundecanol or the condensation of cycloundecanone with an aldehyde. It has potential applications in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals due to its reactive ketone groups and cyclic structure.

Check Digit Verification of cas no

The CAS Registry Mumber 3008-34-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,0 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3008-34:
(6*3)+(5*0)+(4*0)+(3*8)+(2*3)+(1*4)=52
52 % 10 = 2
So 3008-34-2 is a valid CAS Registry Number.

Arynic Condensatiopn of Ketone Enolates. 17. New General Access to Benzocyclobutene Derivatives

Gregoire, Brigitte,Carre, Marie-Christiane,Caubere, Paul

, p. 1419 - 1427 (2007/10/02)

Arynic condensation of 1,2-diketone monoketal enolates appeared to be a very simple way to synthesize benzocyclobutene derivatives.X-ray diffraction and 1H NMR spectra allowed us to determine the structure of the new compounds and to propose a mechanism concerning these condensations.Finally, during this work we devised a new and easily performed two-step synthesis of 1,2-diketones.
