1H-[1,2,4]Triazolo[1,2-a]pyridazine-1,3(2H)-dione, tetrahydro-6,7-bis(methylene)-2-phenyl- is a complex organic compound with the molecular formula C12H11N3O2. It features a triazolo[1,2-a]pyridazine core, which is a fused ring system consisting of a triazole and a pyridazine. The compound is characterized by its tetrahydro structure, indicating four hydrogen atoms attached to the carbon backbone, and the presence of two methylene groups (-CH2-) at the 6 and 7 positions. Additionally, it has a phenyl group (C6H5) attached at the 2 position, which contributes to its aromatic nature. This chemical is known for its potential applications in pharmaceuticals and as a building block in the synthesis of more complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 95884-04-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,8,8 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 95884-04:
(7*9)+(6*5)+(5*8)+(4*8)+(3*4)+(2*0)+(1*4)=181
181 % 10 = 1
So 95884-04-1 is a valid CAS Registry Number.

AZO DIENOPHILES. DIELS-ALDER REACTIONS OF 4-PHENYL-1,2,4-TRIAZOLE-3,5-DIONE AND 5-PHENYLPYRAZOL-3-ONE WITH FUNCTIONALISED DIENES

Johnson, Matthew P.,Moody, Christopher J.

, p. 71 - 74 (2007/10/02)

4-Phenyl-1,2,4-triazole-3,5-dione (PTAD) undergoes a Diels-Alder reaction with a variety of functionalised dienes.The adduct (9) from 2,3-bis(iodomethyl)butadiene gives, on treatment with zinc-copper couple, the diene 2,3,5,6,7,8-hexahydro-6,7-dimethylene-2-phenyl-1H-triazolo-pyridazine-1,3-dione (10) which then reacts with dienophiles in a tandem Diels-Alder reaction.The unsymmetrical azo dienophile, 5-phenylpyrazol-3-one (3), reacts regioselectively with 1-acetoxy-butadiene to give, after hydrolysis, the alcohol 5,8-dihydro-8-hydroxy-3-phenyl-1H-pyrazolo-pyridazin-1-one (19).
