Check Digit Verification of cas no

The CAS Registry Mumber 1233249-54-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,2,4 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1233249-54:
(9*1)+(8*2)+(7*3)+(6*3)+(5*2)+(4*4)+(3*9)+(2*5)+(1*4)=131
131 % 10 = 1
So 1233249-54-1 is a valid CAS Registry Number.

Isoquinoline derivatives as potent CRTH2 antagonists: Design, synthesis and SAR

In this study, we describe the synthesis and structure-activity relationship (SAR) of a series of isoquinoline chemoattractant receptor-homologous molecule expressed on Th2 cells (CRTH2) antagonists. TASP0376377 (15-20), one of the most potent compounds, showed a potent binding affinity (IC50 = 19 nM) in addition to the excellent functional antagonist activity (IC50 = 13 nM). Moreover, the efficacy of this compound in a chemotaxis assay (IC50 = 23 nM) was in good agreement with its potency as a CRTH2 antagonist. In addition, 15-20 exhibited greater selectivity in binding to CRTH2 than to the DP1 prostanoid receptor (IC 50 >1 μM) or the enzymes COX-1 and COX-2 (IC50 >10 μM).

Page/Page column 42, (2011/11/01)

A compound represented by formula (I) or a pharmaceutically acceptable salt thereof has an effect of inhibiting CRTH2 and, therefore, is useful as a preventive or a remedy for allergic diseases such as asthma, atopic dermatitis and allergic rhinitis.
