25759-98-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25759-98-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,5 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 25759-98:
(7*2)+(6*5)+(5*7)+(4*5)+(3*9)+(2*9)+(1*8)=152
152 % 10 = 2
So 25759-98-2 is a valid CAS Registry Number.
