25688-04-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25688-04-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,6,8 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 25688-04:
(7*2)+(6*5)+(5*6)+(4*8)+(3*8)+(2*0)+(1*4)=134
134 % 10 = 4
So 25688-04-4 is a valid CAS Registry Number.
