Check Digit Verification of cas no

The CAS Registry Mumber 398128-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,8,1,2 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 398128-57:
(8*3)+(7*9)+(6*8)+(5*1)+(4*2)+(3*8)+(2*5)+(1*7)=189
189 % 10 = 9
So 398128-57-9 is a valid CAS Registry Number.
