Check Digit Verification of cas no

The CAS Registry Mumber 2404-91-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,0 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2404-91:
(6*2)+(5*4)+(4*0)+(3*4)+(2*9)+(1*1)=63
63 % 10 = 3
So 2404-91-3 is a valid CAS Registry Number.
