Check Digit Verification of cas no

The CAS Registry Mumber 21900-24-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,0 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21900-24:
(7*2)+(6*1)+(5*9)+(4*0)+(3*0)+(2*2)+(1*4)=73
73 % 10 = 3
So 21900-24-3 is a valid CAS Registry Number.

Rational modification of a candidate cancer drug for use against chagas disease

Kraus, James M.,Verlinde, Christophe L. M. J.,Karimi, Mandana,Lepesheva, Galina I.,Gelb, Michael H.,Buckner, Frederick S.

scheme or table, p. 1639 - 1647 (2010/01/07)

Chagas disease is one of the major neglected diseases of the world. Existing drug therapies are limited, ineffective, and highly toxic. We describe a novel strategy of drug discovery of adapting an existing clinical compound with excellent pharmaceutical properties to target a pathogenic organism. The protein farnesyltransferase (PFT) inhibitor tipifarnib, now in phase III anticancer clinical trials, was previously found to kill Trypanosoma cruzi by blocking sterol 14a-demethylase (14DM). We rationally developed tipifarnib analogues that display reduced affinity for human PFT to reduce toxicity while increasing affinity for parasite 14DM. The lead compound has picomolar activity against cultured T. cruzi and is efficacious in a mouse model of acute Chagas disease.
