Check Digit Verification of cas no

The CAS Registry Mumber 1185428-32-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,5,4,2 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1185428-32:
(9*1)+(8*1)+(7*8)+(6*5)+(5*4)+(4*2)+(3*8)+(2*3)+(1*2)=163
163 % 10 = 3
So 1185428-32-3 is a valid CAS Registry Number.
