Check Digit Verification of cas no

The CAS Registry Mumber 949587-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,9,5,8 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 949587-28:
(8*9)+(7*4)+(6*9)+(5*5)+(4*8)+(3*7)+(2*2)+(1*8)=244
244 % 10 = 4
So 949587-28-4 is a valid CAS Registry Number.
