(3aR,3bS,7aR)-5-Hydroxy-2,2,3b,4-tetramethyl-1,2,3a,3b,4,5,6,7a-octahydro-cyclopenta[a]pentalen-3-one is a complex organic compound with a unique molecular structure. It is a derivative of cyclopenta[a]pentalene, a type of pentalenetype sesquiterpene, which is a class of organic compounds derived from isoprene units. This specific compound features a hydroxyl group at the 5-position, and four methyl groups at the 2, 2, 3b, and 4 positions. The stereochemistry of the molecule is defined by the R and S configurations at the 3a, 3b, and 7a positions, respectively. (3aR,3bS,7aR)-5-Hydroxy-2,2,3b,4-tetramethyl-1,2,3a,3b,4,5,6,7a-octahydro-cyclopenta[a]pentalen-3-one is of interest in organic chemistry and may have potential applications in the synthesis of natural products and pharmaceuticals due to its complex and rigid structure.
The CAS Registry Mumber 74145-64-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,4 and 5 respectively; the second part has 2 digits, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 74145-64: (7*7)+(6*4)+(5*1)+(4*4)+(3*5)+(2*6)+(1*4)=125 125 % 10 = 5 So 74145-64-5 is a valid CAS Registry Number.
