19891-74-8 Usage
Definition
ChEBI: A carotenol that is carotenol psi,psi-carotene substituted by a hydroxy group.
Purification Methods
Crystallise lycoxanthin from diethyl ether/light petroleum, *C6H6/pet ether or CS2. Purify it also by chromatography on columns of CaCO3, Ca(OH)2 or deactivated alumina, and washing with *benzene and eluting with 3:1 *C6H6/MeOH. Store it in the dark, in an inert atmosphere, at -20o. The dipalmitate ester crystallises from *C6H6/MeOH and has m 76o. [Beilstein 1 III 2051, 1 IV 2368.]
Check Digit Verification of cas no
The CAS Registry Mumber 19891-74-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,9 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19891-74:
(7*1)+(6*9)+(5*8)+(4*9)+(3*1)+(2*7)+(1*4)=158
158 % 10 = 8
So 19891-74-8 is a valid CAS Registry Number.

Page/Page column 42; 18, (2008/12/08)
A method for synthesizing intermediates for use in the synthesis of carotenoid synthetic intermediates, carotenoid analogs, and/or carotenoid derivatives. The carotenoid analog, derivative, or intermediate may be administered to a subject for the inhibition and/or amelioration of any disease that involves production of reactive oxygen species, reactive nitrogen species, radicals and/or non-radicals. In some embodiments, the invention may include methods for synthesizing chemical compounds including an analog or derivative of a carotenoid. Carotenoid analogs or derivatives may include acyclic end groups. In some embodiments, a carotenoid analog or derivative may include at least one substituent. The substituent may enhance the solubility of the carotenoid analog or derivative such that the carotenoid analog or derivative at least partially dissolves in water.
Carotenoids of higher plants. 5. Total synthesis of lycoxanthin.
