Check Digit Verification of cas no

The CAS Registry Mumber 186809-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,8,0 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 186809-31:
(8*1)+(7*8)+(6*6)+(5*8)+(4*0)+(3*9)+(2*3)+(1*1)=174
174 % 10 = 4
So 186809-31-4 is a valid CAS Registry Number.
