Check Digit Verification of cas no

The CAS Registry Mumber 5981-11-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,8 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5981-11:
(6*5)+(5*9)+(4*8)+(3*1)+(2*1)+(1*1)=113
113 % 10 = 3
So 5981-11-3 is a valid CAS Registry Number.
