25739-65-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25739-65-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,3 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 25739-65:
(7*2)+(6*5)+(5*7)+(4*3)+(3*9)+(2*6)+(1*5)=135
135 % 10 = 5
So 25739-65-5 is a valid CAS Registry Number.
