Ethanone, 1,1'-(1R,2R,3R,4S)-bicyclo[2.2.1]hept-5-ene-2,3-diylbis-, rel-, also known as (1R,2R,3R,4S)-1,1'-(1,2,3,4-tetrahydro-1,2,3,4-tetramethyl-2,3-cyclopentadiene-2,3-diyl)bis(ethanone), is a complex organic compound characterized by its unique bicyclic structure. It features a bicyclo[2.2.1]hept-5-ene core with two ethanone (acetone) groups attached to the 2,3 positions of the cyclopentadiene ring. The compound is a chiral molecule, with the R configuration at all four stereocenters, which contributes to its specific geometric arrangement and potential applications in asymmetric synthesis and as a ligand in catalysis.
The CAS Registry Mumber 3669-58-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,6 and 9 respectively; the second part has 2 digits, 5 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3669-58: (6*3)+(5*6)+(4*6)+(3*9)+(2*5)+(1*8)=117 117 % 10 = 7 So 3669-58-7 is a valid CAS Registry Number.
