Check Digit Verification of cas no

The CAS Registry Mumber 682770-85-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,2,7,7 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 682770-85:
(8*6)+(7*8)+(6*2)+(5*7)+(4*7)+(3*0)+(2*8)+(1*5)=200
200 % 10 = 0
So 682770-85-0 is a valid CAS Registry Number.
