Check Digit Verification of cas no

The CAS Registry Mumber 80478-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,7 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80478-13:
(7*8)+(6*0)+(5*4)+(4*7)+(3*8)+(2*1)+(1*3)=133
133 % 10 = 3
So 80478-13-3 is a valid CAS Registry Number.
