The chemical "10-(tert-butyldimethylsiloxy)-8,9-(di-tert-butylsilylenedioxy)-1-oxo-1,4,4a(S*),9(R*),9a(R*),10(S*)-hexahydroanthracene" is a complex organic compound with a molecular formula of C28H44O4Si2. It features a hexahydroanthracene core, which is a partially saturated derivative of anthracene, a tricyclic aromatic hydrocarbon. The compound is characterized by the presence of a 1-oxo group, indicating the presence of a carbonyl functional group, and a series of siloxy and silylenedioxy groups. Specifically, it has a tert-butyldimethylsiloxy group at the 10-position and a di-tert-butylsilylenedioxy group bridging the 8,9-positions. The stereochemistry at the 4a, 9, and 10 positions is specified as (S*), (R*), and (R*) respectively, indicating the specific three-dimensional arrangement of the atoms. 10-(tert-butyldimethylsiloxy)-8,9-(di-tert-butylsilylenedioxy)-1-oxo-1,4,4a(S*),9(R*),9a(R*),10(S*)-hexahydroanthracene is likely used in advanced organic synthesis, particularly in the formation of complex molecules where the stereochemistry and protecting groups play a crucial role.
The CAS Registry Mumber 86668-46-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,6,6 and 8 respectively; the second part has 2 digits, 4 and 6 respectively. Calculate Digit Verification of CAS Registry Number 86668-46: (7*8)+(6*6)+(5*6)+(4*6)+(3*8)+(2*4)+(1*6)=184 184 % 10 = 4 So 86668-46-4 is a valid CAS Registry Number.
