1-Oxaspiro[4.5]deca-3,6,9-triene-2,8-dione is a complex organic compound with the molecular formula C10H8O3. It is a spiro compound, which means it contains a spiro atom (a central atom connected to three other carbon atoms), and it features a cyclic structure with three double bonds. This molecule is characterized by the presence of a carbonyl group (C=O) at positions 2 and 8, and a lactone ring formed by the oxygen atom connecting the carbon atoms at positions 4 and 5. Due to its unique structure, 1-oxaspiro[4.5]deca-3,6,9-triene-2,8-dione may exhibit interesting chemical properties and potential applications in various fields, such as pharmaceuticals or materials science. However, further research and analysis are required to fully understand its properties and potential uses.

Check Digit Verification of cas no

The CAS Registry Mumber 1899-38-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,9 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1899-38:
(6*1)+(5*8)+(4*9)+(3*9)+(2*3)+(1*8)=123
123 % 10 = 3
So 1899-38-3 is a valid CAS Registry Number.

Gold-catalyzed dearomative spirocyclization of aryl alkynoate esters

Aparece, Mark D.,Vadola, Paul A.

, p. 6008 - 6011 (2014)

Aryl alkynoate esters undergo gold-catalyzed spirocyclization under mild conditions, affording spirolactones in high yields. This approach obviates the need for stoichiometric halogenating reagents typically employed for alkyne activation in related trans
