Check Digit Verification of cas no

The CAS Registry Mumber 21198-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,9 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21198-20:
(7*2)+(6*1)+(5*1)+(4*9)+(3*8)+(2*2)+(1*0)=89
89 % 10 = 9
So 21198-20-9 is a valid CAS Registry Number.
