Check Digit Verification of cas no

The CAS Registry Mumber 1340475-20-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,0,4,7 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1340475-20:
(9*1)+(8*3)+(7*4)+(6*0)+(5*4)+(4*7)+(3*5)+(2*2)+(1*0)=128
128 % 10 = 8
So 1340475-20-8 is a valid CAS Registry Number.
