5034-20-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5034-20-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,3 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5034-20:
(6*5)+(5*0)+(4*3)+(3*4)+(2*2)+(1*0)=58
58 % 10 = 8
So 5034-20-8 is a valid CAS Registry Number.

Inhibition of transforming growth factor β (TGF-β) type 1 receptor (ALK5) provides a feasible approach for the treatment of fibrotic diseases and malignant tumors. In this study, we designed and synthesized a new series of 4-(pyridin-4-oxy)-3-(3,3-difluorocyclobutyl)-pyrazole derivatives, and evaluated biologically as TGF-β type 1 receptor inhibitors. The most potent compound 15r inhibited the ALK5 enzyme and NIH3T3 cell viability with IC50 values of 44 and 42.5 nM, respectively. Compound 15r also displayed better oral plasma exposure and excellent bioavailability than LY-3200882, and in vivo inhibited 65.7% of the tumor growth in a CT26 xenograft mouse model.
