Check Digit Verification of cas no

The CAS Registry Mumber 856417-24-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,4,1 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 856417-24:
(8*8)+(7*5)+(6*6)+(5*4)+(4*1)+(3*7)+(2*2)+(1*4)=188
188 % 10 = 8
