Check Digit Verification of cas no

The CAS Registry Mumber 7691-02-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,9 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7691-02:
(6*7)+(5*6)+(4*9)+(3*1)+(2*0)+(1*2)=113
113 % 10 = 3
So 7691-02-3 is a valid CAS Registry Number.
