898045-05-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 898045-05-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,8,0,4 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 898045-05:
(8*8)+(7*9)+(6*8)+(5*0)+(4*4)+(3*5)+(2*0)+(1*5)=211
211 % 10 = 1
So 898045-05-1 is a valid CAS Registry Number.
