Check Digit Verification of cas no

The CAS Registry Mumber 171178-50-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,1,7 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 171178-50:
(8*1)+(7*7)+(6*1)+(5*1)+(4*7)+(3*8)+(2*5)+(1*0)=130
130 % 10 = 0
So 171178-50-0 is a valid CAS Registry Number.

Synthetic method of 2,6-dihalopyridine-3-carboxylic acid

-

Paragraph 0020, (2019/04/06)

The invention discloses a synthetic method of 2,6-dihalopyridine-3-carboxylic acid and belongs to the field of medicine intermediate synthesis. The synthetic method comprises the following steps: dissolving 2,6-dihalopyridine and Boc2O in an organic solvent; dropwise adding LDA or i-Pr2NMgCl-LiCl to react at a low temperature; then adding an acid-water solution to raise the temperature to react; and adding alkali to adjust pH to obtain 2,6-dihalopyridine-3-carboxylic acid. In addition, by adding LDA into 2,6-dihalopyridine at an ultralow temperature to abstract protons, and then adding DBU-CO2to react and quenching the solution, the 2,6-dihalopyridine-3-carboxylic acid is obtained. The two methods solve the problem that the yield is low by adopting a conventional CO2 introducing method for scaled production and the inter-batch operating repeatability is good.
