898781-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 898781-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,8,7,8 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 898781-99:
(8*8)+(7*9)+(6*8)+(5*7)+(4*8)+(3*1)+(2*9)+(1*9)=272
272 % 10 = 2
So 898781-99-2 is a valid CAS Registry Number.
