Check Digit Verification of cas no
The CAS Registry Mumber 25296-54-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,2,9 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 25296-54:
(7*2)+(6*5)+(5*2)+(4*9)+(3*6)+(2*5)+(1*4)=122
122 % 10 = 2
So 25296-54-2 is a valid CAS Registry Number.
