Check Digit Verification of cas no

The CAS Registry Mumber 449172-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,9,1,7 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 449172-76:
(8*4)+(7*4)+(6*9)+(5*1)+(4*7)+(3*2)+(2*7)+(1*6)=173
173 % 10 = 3
So 449172-76-3 is a valid CAS Registry Number.
