25434-76-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25434-76-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,4,3 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 25434-76:
(7*2)+(6*5)+(5*4)+(4*3)+(3*4)+(2*7)+(1*6)=108
108 % 10 = 8
So 25434-76-8 is a valid CAS Registry Number.
