Check Digit Verification of cas no

The CAS Registry Mumber 220189-04-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,1,8 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 220189-04:
(8*2)+(7*2)+(6*0)+(5*1)+(4*8)+(3*9)+(2*0)+(1*4)=98
98 % 10 = 8
So 220189-04-8 is a valid CAS Registry Number.
