6-Bromo-3-hydroxypyrazine-2-carboxamide is a building block related to Favipiravir(F103350). Favipiravir is used for the treatment of advanced Ebola virus infection in a small animal model. Favipiravir suppressed the replication of Zaire Ebola virus and prevented a lethal outcome in 100% of the animals. Based on the studies, Favipiravir can be a candidate for the treatment of Ebola hemorrhagic fever.

Check Digit Verification of cas no

The CAS Registry Mumber 259793-88-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,9,7,9 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 259793-88:
(8*2)+(7*5)+(6*9)+(5*7)+(4*9)+(3*3)+(2*8)+(1*8)=209
209 % 10 = 9
So 259793-88-9 is a valid CAS Registry Number.
