98399-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98399-92-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,3,9 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98399-92:
(7*9)+(6*8)+(5*3)+(4*9)+(3*9)+(2*9)+(1*2)=209
209 % 10 = 9
So 98399-92-9 is a valid CAS Registry Number.
