Check Digit Verification of cas no
The CAS Registry Mumber 851520-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,5,2 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 851520-85:
(8*8)+(7*5)+(6*1)+(5*5)+(4*2)+(3*0)+(2*8)+(1*5)=159
159 % 10 = 9
So 851520-85-9 is a valid CAS Registry Number.

A series of 4-anilinopyrazolopyridine derivatives were synthesized and biologically evaluated as inhibitors of phosphodiesterase (PDE4). Chemical modification of 3, a structurally new chemical lead that was found in our in-house library, was focused on 1- and 3-substituents. Full details of the discovery of a new orally active chemical lead 5 are presented. Structure-activity relationship data, pharmacological evaluation, and the subtype selectivity study are also presented.
