Check Digit Verification of cas no

The CAS Registry Mumber 40203-66-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,0 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40203-66:
(7*4)+(6*0)+(5*2)+(4*0)+(3*3)+(2*6)+(1*6)=65
65 % 10 = 5
So 40203-66-5 is a valid CAS Registry Number.
