Check Digit Verification of cas no
The CAS Registry Mumber 503-05-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 503-05:
(5*5)+(4*0)+(3*3)+(2*0)+(1*5)=39
39 % 10 = 9
So 503-05-9 is a valid CAS Registry Number.
