25559-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25559-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,5,5 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 25559-57:
(7*2)+(6*5)+(5*5)+(4*5)+(3*9)+(2*5)+(1*7)=133
133 % 10 = 3
So 25559-57-3 is a valid CAS Registry Number.
