Check Digit Verification of cas no

The CAS Registry Mumber 162755-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,7,5 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 162755-28:
(8*1)+(7*6)+(6*2)+(5*7)+(4*5)+(3*5)+(2*2)+(1*8)=144
144 % 10 = 4
So 162755-28-4 is a valid CAS Registry Number.
