Check Digit Verification of cas no

The CAS Registry Mumber 4040-91-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,4 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4040-91:
(6*4)+(5*0)+(4*4)+(3*0)+(2*9)+(1*1)=59
59 % 10 = 9
So 4040-91-9 is a valid CAS Registry Number.
