Check Digit Verification of cas no

The CAS Registry Mumber 5628-28-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,2 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5628-28:
(6*5)+(5*6)+(4*2)+(3*8)+(2*2)+(1*8)=104
104 % 10 = 4
So 5628-28-4 is a valid CAS Registry Number.
