25944-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25944-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,9,4 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25944-40:
(7*2)+(6*5)+(5*9)+(4*4)+(3*4)+(2*4)+(1*0)=125
125 % 10 = 5
So 25944-40-5 is a valid CAS Registry Number.
