Check Digit Verification of cas no

The CAS Registry Mumber 18206-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,0 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18206-22:
(7*1)+(6*8)+(5*2)+(4*0)+(3*6)+(2*2)+(1*2)=89
89 % 10 = 9
So 18206-22-9 is a valid CAS Registry Number.
