Check Digit Verification of cas no

The CAS Registry Mumber 487-72-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,8 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 487-72:
(5*4)+(4*8)+(3*7)+(2*7)+(1*2)=89
89 % 10 = 9
So 487-72-9 is a valid CAS Registry Number.
