Check Digit Verification of cas no

The CAS Registry Mumber 135356-72-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,5 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 135356-72:
(8*1)+(7*3)+(6*5)+(5*3)+(4*5)+(3*6)+(2*7)+(1*2)=128
128 % 10 = 8
