Check Digit Verification of cas no

The CAS Registry Mumber 77589-62-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,8 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77589-62:
(7*7)+(6*7)+(5*5)+(4*8)+(3*9)+(2*6)+(1*2)=189
189 % 10 = 9
