Check Digit Verification of cas no

The CAS Registry Mumber 103186-89-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,1,8 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 103186-89:
(8*1)+(7*0)+(6*3)+(5*1)+(4*8)+(3*6)+(2*8)+(1*9)=106
106 % 10 = 6
So 103186-89-6 is a valid CAS Registry Number.
