Check Digit Verification of cas no

The CAS Registry Mumber 18651-16-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,5 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18651-16:
(7*1)+(6*8)+(5*6)+(4*5)+(3*1)+(2*1)+(1*6)=116
116 % 10 = 6
So 18651-16-6 is a valid CAS Registry Number.
