Check Digit Verification of cas no

The CAS Registry Mumber 21728-28-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,2 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21728-28:
(7*2)+(6*1)+(5*7)+(4*2)+(3*8)+(2*2)+(1*8)=99
99 % 10 = 9
So 21728-28-9 is a valid CAS Registry Number.
