Check Digit Verification of cas no

The CAS Registry Mumber 870636-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,6,3 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 870636-64:
(8*8)+(7*7)+(6*0)+(5*6)+(4*3)+(3*6)+(2*6)+(1*4)=189
189 % 10 = 9
So 870636-64-9 is a valid CAS Registry Number.

C10 Dialdehyde, Synthetic Method Thereof, and Synthetic Method of Beta-Carotene Using the Same

-

Page/Page column 7, (2008/12/04)

The novel intermediate compound which can be efficiently utilized in the synthesis of carotenoid compounds based on the sulfone chemistry, the preparation method of the same, and the practical synthetic process for preparing β-carotene by the use of the above novel compound are disclosed. The synthesis of β-carotene is characterized by the double elimination reactions of the C40 compound containing both the benzenesulfonyl group and the group X (either halogen or ether), which can be prepared by the coupling reaction of the novel C10 dialdehyde with two equivalents of the C15 allylic sulfone, followed by the functional group transformation of the resulting C40 diol either to the corresponding halide or to the ether, to produce the fully conjugated polyene chain.
