Check Digit Verification of cas no

The CAS Registry Mumber 453518-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,3,5,1 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 453518-19:
(8*4)+(7*5)+(6*3)+(5*5)+(4*1)+(3*8)+(2*1)+(1*9)=149
149 % 10 = 9
So 453518-19-9 is a valid CAS Registry Number.
