Check Digit Verification of cas no

The CAS Registry Mumber 6557-16-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,5 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6557-16:
(6*6)+(5*5)+(4*5)+(3*7)+(2*1)+(1*6)=110
110 % 10 = 0
So 6557-16-0 is a valid CAS Registry Number.
