Check Digit Verification of cas no
The CAS Registry Mumber 26313-51-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,3,1 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 26313-51:
(7*2)+(6*6)+(5*3)+(4*1)+(3*3)+(2*5)+(1*1)=89
89 % 10 = 9
So 26313-51-9 is a valid CAS Registry Number.
