Check Digit Verification of cas no

The CAS Registry Mumber 28638-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,3 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28638-80:
(7*2)+(6*8)+(5*6)+(4*3)+(3*8)+(2*8)+(1*0)=144
144 % 10 = 4
So 28638-80-4 is a valid CAS Registry Number.
