The chemical "(10R,13R,17R)-3-Chloro-17-((R)-1,5-dimethyl-hexyl)-10,13-dimethyl-hexadecahydro-cyclopenta[a]phenanthren-6-one oxime" is a complex organic compound with a molecular formula of C27H45ClNO. It is a derivative of hexadecahydro-cyclopenta[a]phenanthren-6-one, featuring a chloro group at the 3rd position, a 1,5-dimethyl-hexyl group at the 17th position, and methyl groups at the 10th and 13th positions. The oxime functional group is present at the 6th position, indicating the presence of a nitrogen-oxygen double bond. (10R,13R,17R)-3-Chloro-17-((R)-1,5-dimethyl-hexyl)-10,13-dimethyl-hexadecahydro-cyclopenta[a]phenanthren-6-one oxime is likely to be found in the field of organic chemistry, potentially as an intermediate in the synthesis of pharmaceuticals or other complex molecules, given its structural complexity and the presence of multiple chiral centers.

Check Digit Verification of cas no

The CAS Registry Mumber 7768-88-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,6 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7768-88:
(6*7)+(5*7)+(4*6)+(3*8)+(2*8)+(1*8)=149
149 % 10 = 9
So 7768-88-9 is a valid CAS Registry Number.

Reaction of Nitrosyl Chloride Gas with Unsaturated Steroids

Shafiullah,Rafiuddin, Ansari M.,Husain, Shakir

, p. 3411 - 3414 (1987)

Reaction of nitrosyl chloride gas at 0 deg C with 3,5-cholestadiene (1) provided 3,6β-dinitro-5-chloro-5α-cholest-3-ene (4) and with 3α,5-cyclo-5α-cholestan-6-one (2) afforded 3β-chloro-5-nitro-5α-cholestan-6-one (7) and 3β-chloro-6-nitrato-5-cholestene (8).Similar reaction with 6-hydroxylimino 3α,5-cyclo-5α-cholestane (3) gave 3β,6-dichloro-6-cholestene (10), 3β-chloro-6-nitratoimino-5α-cholestane (11) and 3β,5-dichloro-6-nitroimino-5β-cholestane (12).Compound 12 upon hydrolysis furnished 3β,5-dichloro-5β-cholestan-6-one (14).The structures of these compounds were established on the basis of their spectral properties, and some pertinent chemical transformations.Mechanisms for the formation of some unusual products are discussed.
