Check Digit Verification of cas no

The CAS Registry Mumber 68559-02-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,5 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 68559-02:
(7*6)+(6*8)+(5*5)+(4*5)+(3*9)+(2*0)+(1*2)=164
164 % 10 = 4
So 68559-02-4 is a valid CAS Registry Number.
