Check Digit Verification of cas no

The CAS Registry Mumber 39984-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,8 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 39984-97:
(7*3)+(6*9)+(5*9)+(4*8)+(3*4)+(2*9)+(1*7)=189
189 % 10 = 9
So 39984-97-9 is a valid CAS Registry Number.
