Check Digit Verification of cas no

The CAS Registry Mumber 422508-26-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,2,5,0 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 422508-26:
(8*4)+(7*2)+(6*2)+(5*5)+(4*0)+(3*8)+(2*2)+(1*6)=117
117 % 10 = 7
So 422508-26-7 is a valid CAS Registry Number.

Development of a purine-scaffold novel class of hsp90 binders that inhibit the proliferation of cancer cells and induce the degradation of Her2 tyrosine kinase

Chiosis, Gabriela,Lucas, Brian,Shtil, Alexander,Huezo, Henri,Rosen, Neal

, p. 3555 - 3564 (2007/10/03)

The first published synthesis and characterization of a purine-scaffold library of hsp90 inhibitors is presented. The purine-scaffold represents a platform for the creation of easily synthesizable and derivatizable soluble molecules that are amenable for oral administration. The most active compound of the series (71) exhibits binding to hsp90 comparable to the natural product derivative 17AAG that is now in Phase I clinical trial as a cancer therapeutic. 71 Induces the degradation of Her2 tyrosine kinase and arrests the MCF-7 breast cancer cell line at low micromolar concentrations (IC50=2 μM).
