Check Digit Verification of cas no

The CAS Registry Mumber 82218-18-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,1 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 82218-18:
(7*8)+(6*2)+(5*2)+(4*1)+(3*8)+(2*1)+(1*8)=116
116 % 10 = 6
So 82218-18-6 is a valid CAS Registry Number.
