Check Digit Verification of cas no

The CAS Registry Mumber 6371-85-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,7 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6371-85:
(6*6)+(5*3)+(4*7)+(3*1)+(2*8)+(1*5)=103
103 % 10 = 3
So 6371-85-3 is a valid CAS Registry Number.
