Check Digit Verification of cas no

The CAS Registry Mumber 180-45-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,8 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 180-45:
(5*1)+(4*8)+(3*0)+(2*4)+(1*5)=50
50 % 10 = 0
So 180-45-0 is a valid CAS Registry Number.
