The chemical compound "(1S,4R,4aR,6aS,7S,11aS,11bS)-4-(tert-Butyl-dimethyl-silanyloxy)-1,4a,7,10,10-pentamethyl-dodecahydro-9,11-dioxa-cyclohepta[a]naphthalen-1-ol" is a complex, chiral molecule with a unique structure. It features a cyclohepta[a]naphthalene core, which is a seven-membered ring fused to a naphthalene system. The molecule is characterized by its pentamethyl substitution, indicating five methyl groups attached to the carbon skeleton. The presence of a tert-butyl-dimethyl-silanyloxy group at the 4-position suggests a silyl ether protecting group, which is often used in organic synthesis to protect hydroxyl groups. The compound also contains a 9,11-dioxa bridge, adding to its structural complexity. This chiral molecule has specific stereochemistry at several carbon centers, as indicated by the R and S configurations. It is likely to be of interest in the field of organic chemistry, particularly in the synthesis of complex natural products or pharmaceuticals, due to its intricate structure and potential for further functionalization.
The CAS Registry Mumber 95682-54-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,6,8 and 2 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 95682-54: (7*9)+(6*5)+(5*6)+(4*8)+(3*2)+(2*5)+(1*4)=175 175 % 10 = 5 So 95682-54-5 is a valid CAS Registry Number.
