Tetrahydro-pyrazolo[1,2-a]pyridazine-5,8-dione is a heterocyclic compound characterized by a pyrazolo[1,2-a]pyridazine core structure, which consists of a pyrazole ring fused to a pyridazine ring. tetrahydro-pyrazolo[1,2-a]pyridazine-5,8-dione is specifically a tetrahydro derivative, meaning it contains four hydrogen atoms incorporated into its structure, which reduces the number of double bonds and increases the saturation of the molecule. The presence of a 5,8-dione functional group indicates two carbonyl groups (C=O) are located at the 5th and 8th positions of the molecule, contributing to its reactivity and potential applications in various chemical and pharmaceutical contexts. tetrahydro-pyrazolo[1,2-a]pyridazine-5,8-dione is of interest in organic chemistry due to its unique structure and the possibility of further functionalization, which can lead to the development of new drugs or other chemical products.
The CAS Registry Mumber 5677-89-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,7 and 7 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 5677-89: (6*5)+(5*6)+(4*7)+(3*7)+(2*8)+(1*9)=134 134 % 10 = 4 So 5677-89-4 is a valid CAS Registry Number.
