25782-24-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25782-24-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,8 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 25782-24:
(7*2)+(6*5)+(5*7)+(4*8)+(3*2)+(2*2)+(1*4)=125
125 % 10 = 5
So 25782-24-5 is a valid CAS Registry Number.
