Check Digit Verification of cas no

The CAS Registry Mumber 249-03-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,4 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 249-03:
(5*2)+(4*4)+(3*9)+(2*0)+(1*3)=56
56 % 10 = 6
So 249-03-6 is a valid CAS Registry Number.
