Check Digit Verification of cas no

The CAS Registry Mumber 1184304-26-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,4,3,0 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1184304-26:
(9*1)+(8*1)+(7*8)+(6*4)+(5*3)+(4*0)+(3*4)+(2*2)+(1*6)=134
134 % 10 = 4
So 1184304-26-4 is a valid CAS Registry Number.

Synthesis and pharmacological evaluation of new pyridazin-based thioderivatives as formyl peptide receptor (FPR) agonists

Preclinical Research A new series of pyridazinone-based thioderivatives and pyridazine analogs was synthesized and tested for their ability to bind to the three human formyl peptide receptor (FPR) isoforms (FPR1, FPR2, and FPR3) and to activate intracellular calcium mobilization and chemotaxis in human neutrophils. Among the pyridazin-3(2H)-one derivatives tested, analogs 8b and 8c were mixed FPR1/FPR2 agonists, with median effective concentration values in the micromolar range, and were able to activate chemotaxis and Ca 2+ flux in human neutrophils in the low micromolar range. Molecular docking studies showed that interaction of a ligand with Arg205 of FPR1 is important for FPR1 agonist activity. For FPR2, differences in activity between oxygen-containing compounds and their thio-analogs were due to steric bulkiness of sulfur-containing groups.
