Check Digit Verification of cas no

The CAS Registry Mumber 71289-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,2,8 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71289-18:
(7*7)+(6*1)+(5*2)+(4*8)+(3*9)+(2*1)+(1*8)=134
134 % 10 = 4
So 71289-18-4 is a valid CAS Registry Number.
