Check Digit Verification of cas no

The CAS Registry Mumber 1443529-80-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,5,2 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1443529-80:
(9*1)+(8*4)+(7*4)+(6*3)+(5*5)+(4*2)+(3*9)+(2*8)+(1*0)=163
163 % 10 = 3
So 1443529-80-3 is a valid CAS Registry Number.
