General Description
(E)-1-(4-METHOXY-2,3,6-TRIMETHYL-PHENYL)-3-METHYL-PENTA-1,4-DIEN-3-OL, also known as isostemofoline, is a chemical compound with a molecular formula C19H26O2. It is a naturally occurring alkaloid found in plants of the Menispermaceae family, particularly in the Tinospora species. Isostemofoline has been studied for its potential medicinal properties, including its antitumor and anti-inflammatory activities. It has also been investigated for its potential as a cholinesterase inhibitor, which could be relevant for the treatment of Alzheimer's disease. Further research is needed to fully understand the pharmacological and therapeutic potential of isostemofoline.
Check Digit Verification of cas no
The CAS Registry Mumber 54757-48-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,7,5 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 54757-48:
(7*5)+(6*4)+(5*7)+(4*5)+(3*7)+(2*4)+(1*8)=151
151 % 10 = 1
So 54757-48-1 is a valid CAS Registry Number.

Page/Page column 9, (2016/04/20)
The present invention provides a process for preparation of {(2E,4E,6E,8E)-9-(4-methoxy-2,3,6- trimethyl)phenyl-3,7-dimethyl-nona-2,4,6,8}tetraenoate, an acitretin intermediate of formula (VI) with trans isomer ≥97%, comprising of reacting 3-formyl-crotonic acid butyl ester of formula (V), substantially free of impurities, with 5-(4-methoxy-2,3,6-trimethylphenyl)-3- methyl-penta-2,4-diene-l-triphenyl phosphonium bromide of formula (IV) and isolating resultant compound of formula (VI), treating the filtrate with iodine for isomerization of the undesired cis intermediate and finally obtaining acitretin (I), with desired trans isomer ≥97%.
