Check Digit Verification of cas no

The CAS Registry Mumber 1130820-87-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,0,8,2 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1130820-87:
(9*1)+(8*1)+(7*3)+(6*0)+(5*8)+(4*2)+(3*0)+(2*8)+(1*7)=109
109 % 10 = 9
So 1130820-87-9 is a valid CAS Registry Number.
