223405-97-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 223405-97-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,4,0 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 223405-97:
(8*2)+(7*2)+(6*3)+(5*4)+(4*0)+(3*5)+(2*9)+(1*7)=108
108 % 10 = 8
So 223405-97-8 is a valid CAS Registry Number.

Methods for synthesis of carotenoids, including analogs, derivatives, and synthetic and biological intermediates

-

Page/Page column 37, (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.
