Check Digit Verification of cas no

The CAS Registry Mumber 54013-40-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,0,1 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 54013-40:
(7*5)+(6*4)+(5*0)+(4*1)+(3*3)+(2*4)+(1*0)=80
80 % 10 = 0
So 54013-40-0 is a valid CAS Registry Number.
