Check Digit Verification of cas no

The CAS Registry Mumber 1218989-13-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,8,9,8 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1218989-13:
(9*1)+(8*2)+(7*1)+(6*8)+(5*9)+(4*8)+(3*9)+(2*1)+(1*3)=189
189 % 10 = 9
So 1218989-13-9 is a valid CAS Registry Number.
