Check Digit Verification of cas no

The CAS Registry Mumber 1143-15-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,4 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1143-15:
(6*1)+(5*1)+(4*4)+(3*3)+(2*1)+(1*5)=43
43 % 10 = 3
So 1143-15-3 is a valid CAS Registry Number.
