Check Digit Verification of cas no

The CAS Registry Mumber 209-21-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 209-21:
(5*2)+(4*0)+(3*9)+(2*2)+(1*1)=42
42 % 10 = 2
So 209-21-2 is a valid CAS Registry Number.
