Prednisone derivative. An antiviral compound. Corticosteroid.Check Digit Verification of cas no
The CAS Registry Mumber 70522-55-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,2 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.Calculate Digit Verification of CAS Registry Number 70522-55:
(7*7)+(6*0)+(5*5)+(4*2)+(3*2)+(2*5)+(1*5)=103
103 % 10 = 3
So 70522-55-3 is a valid CAS Registry Number.
