Check Digit Verification of cas no

The CAS Registry Mumber 143-52-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143-52:
(5*1)+(4*4)+(3*3)+(2*5)+(1*2)=42
42 % 10 = 2
So 143-52-2 is a valid CAS Registry Number.
