Check Digit Verification of cas no

The CAS Registry Mumber 75509-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,0 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75509-02:
(7*7)+(6*5)+(5*5)+(4*0)+(3*9)+(2*0)+(1*2)=133
133 % 10 = 3
So 75509-02-3 is a valid CAS Registry Number.
