Check Digit Verification of cas no

The CAS Registry Mumber 82701-07-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,7,0 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82701-07:
(7*8)+(6*2)+(5*7)+(4*0)+(3*1)+(2*0)+(1*7)=113
113 % 10 = 3
So 82701-07-3 is a valid CAS Registry Number.
