77422-99-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77422-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,2 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77422-99:
(7*7)+(6*7)+(5*4)+(4*2)+(3*2)+(2*9)+(1*9)=152
152 % 10 = 2
So 77422-99-2 is a valid CAS Registry Number.

Sircar, Jagadish C.,Capiris, Thomas,Kesten, Stephen J.,Herzig, David J.

, p. 735 - 742 (2007/10/02)

A new series of antiallergic agents, pyrazoloquinazolin-9-ones, was synthesized and evaluated for inhibitory effects in the rat reaginic passive cutaneous anaphylaxis (PCA) screen.Several analogues were found to be more potent than cromolyn sodium intravenously.Structure-activity relationships are discussed.One of the compounds, 4,9-dihydro-5-methoxy-9-oxopyrazoloquinazoline-2-carboxylic acid (36), was found to be approximately 250 times more potent than cromolyn sodium intravenously.
