Check Digit Verification of cas no

The CAS Registry Mumber 909914-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,9,1 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 909914-28:
(8*9)+(7*0)+(6*9)+(5*9)+(4*1)+(3*4)+(2*2)+(1*8)=199
199 % 10 = 9
So 909914-28-9 is a valid CAS Registry Number.
