The chemical compound "(5S,10R,13R,17R)-17-((R)-1,5-Dimethyl-hexyl)-3-hydroxy-10,13-dimethyl-hexadecahydro-cyclopenta[a]phenanthren-6-one oxime" is a complex organic molecule with a unique structure. It features a cyclopenta[a]phenanthren-6-one core, which is a type of polycyclic aromatic hydrocarbon. The molecule is characterized by its chiral centers at the 5th, 10th, 13th, and 17th positions, with the specific configuration being (5S,10R,13R,17R). It also contains a 3-hydroxy group and two methyl groups at the 10th and 13th positions. The 17th position is substituted with a (R)-1,5-dimethyl-hexyl group, which adds to the molecule's complexity. The presence of an oxime group at the 6th position further distinguishes (5S,10R,13R,17R)-17-((R)-1,5-Dimethyl-hexyl)-3-hydroxy-10,13-dimethyl-hexadecahydro-cyclopenta[a]phenanthren-6-one oxime. This chemical is likely to be found in specialized applications due to its intricate structure, possibly in the field of pharmaceuticals or as a synthetic intermediate in organic chemistry.
The CAS Registry Mumber 986-48-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,8 and 6 respectively; the second part has 2 digits, 4 and 8 respectively. Calculate Digit Verification of CAS Registry Number 986-48: (5*9)+(4*8)+(3*6)+(2*4)+(1*8)=111 111 % 10 = 1 So 986-48-1 is a valid CAS Registry Number.
