Check Digit Verification of cas no

The CAS Registry Mumber 1188381-83-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,8,3,8 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1188381-83:
(9*1)+(8*1)+(7*8)+(6*8)+(5*3)+(4*8)+(3*1)+(2*8)+(1*3)=190
190 % 10 = 0
So 1188381-83-0 is a valid CAS Registry Number.
