(1S,4R)-8,8-Dimethyl-4,4a,5,7a-tetrahydro-1H-1,4-methano-cyclopenta[d]pyridazine is a complex organic compound with a unique molecular structure. It is characterized by a cyclopenta[d]pyridazine core, which is a fused ring system consisting of a cyclopentane and a pyridazine. The compound has a tetrahydro prefix, indicating that it contains four hydrogen atoms in a saturated ring structure. The 8,8-dimethyl groups are located at the 8th carbon position, contributing to the molecule's steric hindrance and electronic properties. The stereochemistry is defined by the (1S,4R) configuration, which specifies the three-dimensional arrangement of atoms around the chiral centers at the 1st and 4th positions. (1S,4R)-8,8-Dimethyl-4,4a,5,7a-tetrahydro-1H-1,4-methano-cyclopenta[d]pyridazine is of interest in the field of organic chemistry, potentially for its unique reactivity or as a building block in the synthesis of more complex molecules.
The CAS Registry Mumber 89718-42-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,1 and 8 respectively; the second part has 2 digits, 4 and 2 respectively. Calculate Digit Verification of CAS Registry Number 89718-42: (7*8)+(6*9)+(5*7)+(4*1)+(3*8)+(2*4)+(1*2)=183 183 % 10 = 3 So 89718-42-3 is a valid CAS Registry Number.
