Check Digit Verification of cas no

The CAS Registry Mumber 65516-41-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,5,1 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 65516-41:
(7*6)+(6*5)+(5*5)+(4*1)+(3*6)+(2*4)+(1*1)=128
128 % 10 = 8
So 65516-41-8 is a valid CAS Registry Number.
