Check Digit Verification of cas no

The CAS Registry Mumber 931089-00-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,1,0,8 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 931089-00:
(8*9)+(7*3)+(6*1)+(5*0)+(4*8)+(3*9)+(2*0)+(1*0)=158
158 % 10 = 8
