25506-69-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25506-69-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,5,0 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 25506-69:
(7*2)+(6*5)+(5*5)+(4*0)+(3*6)+(2*6)+(1*9)=108
108 % 10 = 8
So 25506-69-8 is a valid CAS Registry Number.
