Check Digit Verification of cas no

The CAS Registry Mumber 109531-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,5,3 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109531-18:
(8*1)+(7*0)+(6*9)+(5*5)+(4*3)+(3*1)+(2*1)+(1*8)=112
112 % 10 = 2
So 109531-18-2 is a valid CAS Registry Number.
