Check Digit Verification of cas no

The CAS Registry Mumber 67818-06-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,8,1 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 67818-06:
(7*6)+(6*7)+(5*8)+(4*1)+(3*8)+(2*0)+(1*6)=158
158 % 10 = 8
So 67818-06-8 is a valid CAS Registry Number.
