The chemical compound "(3S,8S,9S,10R,13S,14S,17R)-10,13-Dimethyl-17-[(S)-1-((2S,5S)-5-methyl-piperidin-2-yl)-ethyl]-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthrene-3,16-diol" is a complex, chiral molecule with a unique structure. It features a cyclopenta[a]phenanthrene core, which is a type of polycyclic aromatic hydrocarbon, and is further modified with various methyl groups and a piperidine ring attached to an ethyl chain. The compound's stereochemistry is defined by the presence of multiple chiral centers, indicated by the 'S' and 'R' prefixes, which denote the specific three-dimensional arrangement of atoms around these centers. This molecule is an example of the intricate and specific structures found in natural products and can be relevant in the fields of organic chemistry, pharmacology, and materials science.

Check Digit Verification of cas no

The CAS Registry Mumber 1176-36-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,7 and 6 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1176-36:
(6*1)+(5*1)+(4*7)+(3*6)+(2*3)+(1*6)=69
69 % 10 = 9
So 1176-36-9 is a valid CAS Registry Number.

Partial Synthesis of the Steroid Alkaloids Teinemine, 22-Isoteinemine, Etioline, and 25-Isoetioline

Quyen, Le thi,Ripperger, Helmut,Schreiber, Klaus

, p. 143 - 149 (2007/10/02)

The rare 16α-hydroxylated steroid alkaloids teinemine , 22-isoteinemine , etioline , and 25-isoetioline are synthesized from the abundant spirosolane alkaloids tomatid-5-en-3β-ol and solasodine , respectively.The crucial stages of these syntheses are the conversion of 1 or 15 into the N-protected (22S,25S)-, (22R,25S)-, and (22S,25R) -22,26-epimino-3β-hydroxycholest-5-en-16-ones 6, 7, and 18 as well as their reductions with sodium/2-propanol to the 16α-hydroxy compounds teinemine (8), 22-isoteinemine (10), and (22S,25R)-22,26-epiminocholest-5-ene-3β,16α-diol (19), respectively.By treatment with sodium methanolate the N-chloro derivatives 9 and 11 of 8 and 10 afford etioline (12).In an analogous manner, the N-chloro derivative 20 of 19 is converted into 25-isoetioline (21).
