Check Digit Verification of cas no

The CAS Registry Mumber 143505-42-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,0 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143505-42:
(8*1)+(7*4)+(6*3)+(5*5)+(4*0)+(3*5)+(2*4)+(1*2)=104
104 % 10 = 4
So 143505-42-4 is a valid CAS Registry Number.
