Check Digit Verification of cas no
The CAS Registry Mumber 20170-32-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,7 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20170-32:
(7*2)+(6*0)+(5*1)+(4*7)+(3*0)+(2*3)+(1*2)=55
55 % 10 = 5
So 20170-32-5 is a valid CAS Registry Number.

Paragraph 0043; 0050-0053; 0064; 0067; 0072; 0075, (2019/11/20)
The invention belongs to the technical field of antioxygens, and particularly relates to a hindered phenol and acylamino intramolecular composite difunctional antioxygen and a synthesis method thereof. The hindered phenol and acylamino intramolecular composite difunctional antioxygen is prepared through the mode that firstly, ethanediamine, methyl alcohol and methyl acrylate are prepared into an ethanediamine dendritic molecule framework, and then the end group of the ethanediamine dendritic molecule framework is subjected to DtBHP closing. The antioxygen forms stable free radicals to end a chain reaction by capturing generated free radicals, the free radicals can be directly, effectively and quickly captured, and the antioxygen is high in antioxygenic capacity.

Initialized from the scaffold of CGP7930, an allosteric agonist of GABAB receptors, a series of noncompetitive antagonists were discovered. Among these compounds, compounds 3, 6, and 14 decreased agonist GABA-induced maximal effect of IP3 production in HEK293 cells overexpressing GABAB receptors and Gqi9 proteins without changing the EC50. Compounds 3, 6, and 14 not only inhibited agonist baclofen-induced ERK1/2 phosphorylation but also blocked CGP7930-induced ERK1/2 phosphorylation in HEK293 cells overexpressing GABAB receptors. The results suggested that compounds 3, 6, and 14 are negative allosteric modulators of GABAB receptors. The representative compound 14 decreased GABA-induced IP3 production with IC50 of 37.9 μM and had no effect on other GPCR Class C members such as mGluR1, mGluR2, and mGluR5. Finally, we showed that compound 14 did not bind to the orthosteric binding sites of GABAB receptors, demonstrating that compound 14 negatively modulated GABAB receptors activity as a negative allosteric modulator.
