Check Digit Verification of cas no

The CAS Registry Mumber 6618-17-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,1 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6618-17:
(6*6)+(5*6)+(4*1)+(3*8)+(2*1)+(1*7)=103
103 % 10 = 3
So 6618-17-3 is a valid CAS Registry Number.
