Check Digit Verification of cas no
The CAS Registry Mumber 4540-00-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,4 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4540-00:
(6*4)+(5*5)+(4*4)+(3*0)+(2*0)+(1*0)=65
65 % 10 = 5
So 4540-00-5 is a valid CAS Registry Number.
