Check Digit Verification of cas no

The CAS Registry Mumber 669053-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,0,5 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 669053-64:
(8*6)+(7*6)+(6*9)+(5*0)+(4*5)+(3*3)+(2*6)+(1*4)=189
189 % 10 = 9
So 669053-64-9 is a valid CAS Registry Number.
