Check Digit Verification of cas no

The CAS Registry Mumber 954221-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,4,2,2 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 954221-28:
(8*9)+(7*5)+(6*4)+(5*2)+(4*2)+(3*1)+(2*2)+(1*8)=164
164 % 10 = 4
So 954221-28-4 is a valid CAS Registry Number.
