Check Digit Verification of cas no

The CAS Registry Mumber 568-02-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 568-02:
(5*5)+(4*6)+(3*8)+(2*0)+(1*2)=75
75 % 10 = 5
So 568-02-5 is a valid CAS Registry Number.
