The chemical compound "(3aR,4R,6aS)-4-[(1E,3S)-3-(tert-butyl-dimethylsilanyloxy)-oct-1-enyl]-3,3a,4,6a-tetrahydro-cyclopenta[b]furan-2-one" is a complex, chiral organic molecule with a unique structure. It features a cyclopenta[b]furan-2-one core, which is a five-membered ring fused to a furan ring, and a tetrahydro structure, indicating the presence of four hydrogen atoms attached to the carbon atoms. The compound also includes a chiral center at the 3a, 4, and 6a positions, with the specific configuration being (3aR,4R,6aS). A notable feature is the presence of a tert-butyl-dimethylsilanyloxy group attached to an oct-1-enyl chain, which extends from the 4-position of the cyclopenta[b]furan-2-one core. This group provides steric hindrance and may influence the compound's reactivity and physical properties. The compound's structure is characterized by a combination of single and double bonds, with the double bond present in the 1E,3S configuration, indicating the specific arrangement of the double bond and the chiral center at the third carbon of the oct-1-enyl chain. This complex structure likely contributes to the compound's specific chemical properties and potential applications in fields such as pharmaceuticals or materials science.

Check Digit Verification of cas no

The CAS Registry Mumber 87727-92-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,2 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 87727-92:
(7*8)+(6*7)+(5*7)+(4*2)+(3*7)+(2*9)+(1*2)=182
182 % 10 = 2
So 87727-92-2 is a valid CAS Registry Number.

Enantiocomplementary Total Asymmetric Syntheses of Prostaglandin A2

Newton, Roger F.,Reynolds, Derek P.,Davies, John,Kay, Paul B.,Roberts, Stanley M,Wallace, Timothy W.

, p. 683 - 686 (2007/10/02)

Both enantiomers of the racemic ketone (4) have been converted into (+)-PGA2 by utilizing two different synthetic pathways.In one route the reaction of the strained tricyclic ketone (8) with the cuprate reagent (9) was the critical step, while in the ' enantiocomplementary ' process the SN' reaction of the same cuprate reagent with the epoxide (16) was the crucial transformation.
