Check Digit Verification of cas no

The CAS Registry Mumber 55512-68-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,1 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55512-68:
(7*5)+(6*5)+(5*5)+(4*1)+(3*2)+(2*6)+(1*8)=120
120 % 10 = 0
So 55512-68-0 is a valid CAS Registry Number.
