Check Digit Verification of cas no
The CAS Registry Mumber 81113-26-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,1 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81113-26:
(7*8)+(6*1)+(5*1)+(4*1)+(3*3)+(2*2)+(1*6)=90
90 % 10 = 0
So 81113-26-0 is a valid CAS Registry Number.
