Check Digit Verification of cas no

The CAS Registry Mumber 259183-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,9,1,8 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 259183-99:
(8*2)+(7*5)+(6*9)+(5*1)+(4*8)+(3*3)+(2*9)+(1*9)=178
178 % 10 = 8
