Check Digit Verification of cas no

The CAS Registry Mumber 143209-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,0 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 143209-53:
(8*1)+(7*4)+(6*3)+(5*2)+(4*0)+(3*9)+(2*5)+(1*3)=104
104 % 10 = 4
So 143209-53-4 is a valid CAS Registry Number.
