Check Digit Verification of cas no

The CAS Registry Mumber 685-03-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 685-03:
(5*6)+(4*8)+(3*5)+(2*0)+(1*3)=80
80 % 10 = 0
So 685-03-0 is a valid CAS Registry Number.
