98993-75-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98993-75-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,9,9 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98993-75:
(7*9)+(6*8)+(5*9)+(4*9)+(3*3)+(2*7)+(1*5)=220
220 % 10 = 0
So 98993-75-0 is a valid CAS Registry Number.
