Check Digit Verification of cas no

The CAS Registry Mumber 157843-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,8,4 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 157843-41:
(8*1)+(7*5)+(6*7)+(5*8)+(4*4)+(3*3)+(2*4)+(1*1)=159
159 % 10 = 9
So 157843-41-9 is a valid CAS Registry Number.

Preparation method of 2-chloro-4-nitrobenzene-alpha-L-fucoside

-

Paragraph 0009; 0033; 0038-0039; 0042; 0047-0048; 0050; ..., (2021/10/11)

The invention discloses a preparation method of 2-chloro-4-nitrobenzene-alpha-L-fucoside, and belongs to the field of in vitro diagnosis. The preparation method comprises the following steps: taking L-fucose as an initial raw material, carrying out acetylation reaction to prepare 1, 2, 3, 4-tetraacetyl-alpha-L-fucose, and then carrying out glycosylation reaction on the 1, 2, 3, 4-tetraacetyl-alpha-L-fucose and 2-chloro-4-nitrophenol to prepare the 2-chloro-4-nitrobenzene-2, 3, 4-triacetyl-alpha-L-fucoside, the catalyst is selected from Trimethylsilyl trifluoromethanesulfonate or Boron trifluoride ethyl ether; and finally, carrying out a deacetylation reaction, so as to prepare the 2-chloro-4-nitrobenzene-alpha-L-fucoside. The method disclosed by the invention is relatively short in reaction route, and the final product is prepared through three-step reaction; L-fucose is used as the raw material, the price of the initial raw material is relatively low, and the dosage of 2-chloro-4-nitrophenol is obviously reduced; the post-treatment process is simple, the reaction reproducibility is good, and industrial production can be realized.
