Check Digit Verification of cas no

The CAS Registry Mumber 140473-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,4,7 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140473-30:
(8*1)+(7*4)+(6*0)+(5*4)+(4*7)+(3*3)+(2*3)+(1*0)=99
99 % 10 = 9
So 140473-30-9 is a valid CAS Registry Number.
