Check Digit Verification of cas no

The CAS Registry Mumber 5519-45-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,1 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5519-45:
(6*5)+(5*5)+(4*1)+(3*9)+(2*4)+(1*5)=99
99 % 10 = 9
So 5519-45-9 is a valid CAS Registry Number.
