Check Digit Verification of cas no

The CAS Registry Mumber 58540-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,5,4 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 58540-89:
(7*5)+(6*8)+(5*5)+(4*4)+(3*0)+(2*8)+(1*9)=149
149 % 10 = 9
So 58540-89-9 is a valid CAS Registry Number.
