The chemical compound "(E)-1α,7,8,11,12,13β,14,15-Octahydro-3,10,14,14-tetramethyl-4,5-benzo-3-aza-6-thia-2H-bicyclo<11.2.0>pentadecen-2-one" is a complex, cyclic organic molecule with a unique structure. It features an octahydro (eight hydrogen atoms) framework, with a bicyclo (two fused rings) system that includes a benzene ring and a 3-aza (nitrogen-containing) component. The molecule also contains a 6-thia (sulfur-containing) group, which adds to its complexity. The compound is characterized by its stereochemistry, with specific hydrogen atoms positioned in alpha (α) and beta (β) configurations, and the presence of four methyl groups at different carbon positions. (E)-1α,7,8,11,12,13β,14,15-Octahydro-3,10,14,14-tetramethyl-4,5-benzo-3-aza-6-thia-2H-bicyclo<11.2.0>pentadecen-2-one is likely to have specific applications in fields such as pharmaceuticals or chemical research, given its intricate structure and potential for interaction with biological targets.
The CAS Registry Mumber 90191-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,9 and 1 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 90191-54: (7*9)+(6*0)+(5*1)+(4*9)+(3*1)+(2*5)+(1*4)=121 121 % 10 = 1 So 90191-54-1 is a valid CAS Registry Number.
