Check Digit Verification of cas no

The CAS Registry Mumber 86569-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,5,6 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 86569-77:
(7*8)+(6*6)+(5*5)+(4*6)+(3*9)+(2*7)+(1*7)=189
189 % 10 = 9
So 86569-77-9 is a valid CAS Registry Number.
