Check Digit Verification of cas no

The CAS Registry Mumber 80149-75-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,1,4 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80149-75:
(7*8)+(6*0)+(5*1)+(4*4)+(3*9)+(2*7)+(1*5)=123
123 % 10 = 3
So 80149-75-3 is a valid CAS Registry Number.
