Check Digit Verification of cas no

The CAS Registry Mumber 321918-08-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,9,1 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 321918-08:
(8*3)+(7*2)+(6*1)+(5*9)+(4*1)+(3*8)+(2*0)+(1*8)=125
125 % 10 = 5
So 321918-08-5 is a valid CAS Registry Number.
