Check Digit Verification of cas no

The CAS Registry Mumber 73028-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,0,2 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 73028-08:
(7*7)+(6*3)+(5*0)+(4*2)+(3*8)+(2*0)+(1*8)=107
107 % 10 = 7
So 73028-08-7 is a valid CAS Registry Number.
