Check Digit Verification of cas no
The CAS Registry Mumber 13324-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,2 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13324-20:
(7*1)+(6*3)+(5*3)+(4*2)+(3*4)+(2*2)+(1*0)=64
64 % 10 = 4
So 13324-20-4 is a valid CAS Registry Number.

Discovery of potent competitive antagonists and positive modulators of the P2X2 receptor

Evaluation and optimization of anthraquinone derivatives related to Reactive Blue 2 at P2X2 receptors yielded the first potent and selective P2X2 receptor antagonists. The compounds were tested for inhibition of ATP (10 μM) mediated currents in Xenopus oocytes expressing the rat P2X2 receptor. The most potent antagonists were sodium 1-amino-4-[3-(4,6-dichloro[1,3,5]triazine-2- ylamino)phenylamino]- 9,10-dioxo-9,10-dihydroanthracene-2-sulfonate (63, PSB-10211, IC50 8 6 nM) and disodium 1-amino- 4-[3-(4,6-dichloro[1,3, 5]triazine-2-ylamino)-4-sulfophenylamino]-9,10-dioxo-9,10-dihydroanthracene- 2-sulfonate (57, PSB-1011, IC50 79 nM). Compound 57 exhibited a competitive mechanism of action (pA2 7.49). It was >100-fold selective versus P2X4, P2X7, and several investigated P2Y receptor subtypes (P2Y24612); selectivity versus P2X1 and P2X3 receptors was moderate (>5-fold). Compound 57 was >13-fold more potent at the homomeric P2X2 than at the heteromeric P2X2/3 receptor. Several anthraquinone derivatives were found to act as positive modulators of ATP effects at P2X2 receptors, for example, sodium 1-amino-4-(3-phenoxyphenylamino)-9,10-dioxo-9,10- dihydroanthracene-2-sulfonate (51, PSB-10129, EC50 489 nM), which led to about a 3-fold increase in the ATP-elicited current.
