Check Digit Verification of cas no

The CAS Registry Mumber 1031428-76-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,1,4,2 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1031428-76:
(9*1)+(8*0)+(7*3)+(6*1)+(5*4)+(4*2)+(3*8)+(2*7)+(1*6)=108
108 % 10 = 8
So 1031428-76-8 is a valid CAS Registry Number.
