878-80-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 878-80-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 878-80:
(5*8)+(4*7)+(3*8)+(2*8)+(1*0)=108
108 % 10 = 8
So 878-80-8 is a valid CAS Registry Number.
