Check Digit Verification of cas no

The CAS Registry Mumber 220657-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,6,5 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 220657-28:
(8*2)+(7*2)+(6*0)+(5*6)+(4*5)+(3*7)+(2*2)+(1*8)=113
113 % 10 = 3
So 220657-28-3 is a valid CAS Registry Number.
