Check Digit Verification of cas no
The CAS Registry Mumber 25797-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,9 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25797-81:
(7*2)+(6*5)+(5*7)+(4*9)+(3*7)+(2*8)+(1*1)=153
153 % 10 = 3
So 25797-81-3 is a valid CAS Registry Number.
