Check Digit Verification of cas no

The CAS Registry Mumber 251577-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,5,7 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 251577-90:
(8*2)+(7*5)+(6*1)+(5*5)+(4*7)+(3*7)+(2*9)+(1*0)=149
149 % 10 = 9
So 251577-90-9 is a valid CAS Registry Number.

Novel furanylarylene arylsulfonylindolesulfonamides: Synthesis and their antibacterial evaluation

Ramalingan, Chennan,Lee, In-Sook,Kwak, Young-Woo

experimental part, p. 591 - 596 (2009/12/27)

An array of furanylarylene arylsulfonylindolesulfonamides was synthesized through multi-step synthetic protocols involving bromination, stannylation, Stille cross coupling, reduction, arylsulfonylation, chlorosulfonylation, and condensation reactions. As

The activity of diguanidino and 'reversed' diamidino 2,5-diarylfurans versus Trypanosoma cruzi and Leishmania donovani

Stephens, Chad E.,Brun, Reto,Salem, Manar M.,Werbovetz, Karl A.,Tanious, Farial,Wilson, W. David,Boykin, David W.

, p. 2065 - 2069 (2007/10/03)

The in vitro activity of 20 dicationic molecules containing either diguanidino or reversed amidine cationic groups were evaluated versus Trypanosoma cruzi and Leishmania donovani. The most active compounds were in the reversed amidine series and six exhibited IC50 values of less than 1 μmol versus T. cruzi and five gave similar values versus L. donovani.
