1. Rifamycin SV Sodium (Rifaximin EP Impurity C) is a semi-synthetic antibiotic derived from Rifamycin S. (1) Antibacterial (2). Potency >900 units (dry basis).
2. Semi-synthetic antibiotic derived from Rifamycin S. Antibacterial. Potency >900 units (dry basis).

Check Digit Verification of cas no

The CAS Registry Mumber 14897-39-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,8,9 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 14897-39:
(7*1)+(6*4)+(5*8)+(4*9)+(3*7)+(2*3)+(1*9)=143
143 % 10 = 3
So 14897-39-3 is a valid CAS Registry Number.
