Check Digit Verification of cas no
The CAS Registry Mumber 50689-17-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,6,8 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 50689-17:
(7*5)+(6*0)+(5*6)+(4*8)+(3*9)+(2*1)+(1*7)=133
133 % 10 = 3
So 50689-17-3 is a valid CAS Registry Number.

Decarboxylation method for heterocyclic carboxylic acid compounds
-
Paragraph 0036; 0037; 0041, (2019/05/11)
The invention relates to a decarboxylation method for heterocyclic carboxylic acid compounds. The method comprises the following steps: dissolving the heterocyclic carboxylic acid compounds in an aprotic polar solvent N,N-dimethylformamide, and performing decarboxylation at 85-150 DEG C with an organic acid as a catalyst. The method in the invention allows the yield of decarboxylation products obtained after a reaction to be higher than the yield of the products obtained through decarboxylation methods in the prior art, and does not need an expensive metal catalyst; and the solvent (DMF) in the present invention is more stable than DMSO, is not prone to decompose at a high temperature, and it can be recycled, so the cost is reduced. The method has the advantages of simple operation process, zero pollution, greenness, environmental protection and excellent application prospect.
