Check Digit Verification of cas no

The CAS Registry Mumber 72028-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,2 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 72028-22:
(7*7)+(6*2)+(5*0)+(4*2)+(3*8)+(2*2)+(1*2)=99
99 % 10 = 9
So 72028-22-9 is a valid CAS Registry Number.
