The chemical compound "(3R,5R,6S,8S,9S,10R,13S,14S)-3-(tert-Butyl-dimethyl-silanyloxy)-17-[(S)-1-((R)-4,5-dimethyl-6-oxo-3,6-dihydro-2H-pyran-2-yl)-ethyl]-10,13-dimethyl-tetradecahydro-20-oxa-cyclopropa[5,6]cyclopenta[a]phenanthren-1-one" is a complex, chiral molecule with a unique structure. It features a cyclopropa[5,6]cyclopenta[a]phenanthren-1-one core, which is a type of polycyclic aromatic hydrocarbon. The molecule is characterized by its tetradecahydro (14-carbon) framework, with specific stereochemistry at several carbon centers, indicated by the R and S prefixes. It also includes a tert-butyl-dimethyl-silanyloxy group at the 3-position, which is a protecting group often used in organic synthesis to shield hydroxyl groups. Additionally, it has a 17-ethyl side chain that is substituted with a (R)-4,5-dimethyl-6-oxo-3,6-dihydro-2H-pyran-2-yl group, adding to its complexity. (3R,5R,6S,8S,9S,10R,13S,14S)-3-(tert-Butyl-dimethyl-silanyloxy)-17-[(S)-1-((R)-4,5-dimethyl-6-oxo-3,6-dihydro-2H-pyran-2-yl)-ethyl]-10,13-dimethyl-tetradecahydro-20-oxa-cyclopropa[5,6]cyclopenta[a]phenanthren-1-one is likely to be found in advanced pharmaceutical or chemical research due to its intricate structure and potential for specific interactions in biological systems.

Check Digit Verification of cas no

The CAS Registry Mumber 85427-88-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,4,2 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 85427-88:
(7*8)+(6*5)+(5*4)+(4*2)+(3*7)+(2*8)+(1*8)=159
159 % 10 = 9
So 85427-88-9 is a valid CAS Registry Number.
