2-oxabenzo[cd]azulene is a heterocyclic aromatic compound characterized by a unique structure that fuses a benzene ring with an azulene system through a carbonyl group. This molecule features a seven-membered ring with alternating double bonds, similar to azulene, but with an additional oxygen atom incorporated into the ring, creating a carbonyl group. The presence of this oxygen atom significantly influences the electronic properties and reactivity of the molecule, making it a subject of interest in organic chemistry and potentially useful in the synthesis of various pharmaceuticals and materials. The compound's编号 and structural features contribute to its distinct chemical behavior and potential applications in diverse fields.

Check Digit Verification of cas no

The CAS Registry Mumber 209-53-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 209-53:
(5*2)+(4*0)+(3*9)+(2*5)+(1*3)=50
50 % 10 = 0
So 209-53-0 is a valid CAS Registry Number.
