Check Digit Verification of cas no
The CAS Registry Mumber 81263-18-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,6 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81263-18:
(7*8)+(6*1)+(5*2)+(4*6)+(3*3)+(2*1)+(1*8)=115
115 % 10 = 5
So 81263-18-5 is a valid CAS Registry Number.
