359010-60-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 359010-60-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,9,0,1 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 359010-60:
(8*3)+(7*5)+(6*9)+(5*0)+(4*1)+(3*0)+(2*6)+(1*0)=129
129 % 10 = 9
So 359010-60-9 is a valid CAS Registry Number.

Process for preparing carotenoid polyene chain compounds and intermediates for preparing the same

-

, (2008/06/13)

The present invention provides an intermediate compound used for synthesis of polyene chain structure, that is an important moiety of carotenoid compounds, a process for preparing the same, and carotenoid polyene chain compounds prepared by using the intermediate, and, in particular, a process for preparing lycopene. The process for preparing the carotenoid polyene chain compound employs an allylic sulfone compound as starting material, which is reacted with C-5 sulfide compound to extend the carbon chain. The resultant thio-sulfone compound is oxidized, and the obtained disulfone compound is combined with C-10 di(haloallylic) sulfide compound to form a chain compound containing the desired number of carbon atoms. Then, the diallylic sulfone obtained by oxidation of the diallylic sulfide is subjected to Ramberg-Baklund reaction in order to form the central triene bond. After removal of sulfonyl groups, carotenoid polyene chain compound is obtained.
