99698-93-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99698-93-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,9 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99698-93:
(7*9)+(6*9)+(5*6)+(4*9)+(3*8)+(2*9)+(1*3)=228
228 % 10 = 8
So 99698-93-8 is a valid CAS Registry Number.
