Check Digit Verification of cas no
The CAS Registry Mumber 518-40-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 518-40:
(5*5)+(4*1)+(3*8)+(2*4)+(1*0)=61
61 % 10 = 1
So 518-40-1 is a valid CAS Registry Number.
