25303-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25303-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,3,0 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25303-41:
(7*2)+(6*5)+(5*3)+(4*0)+(3*3)+(2*4)+(1*1)=77
77 % 10 = 7
So 25303-41-7 is a valid CAS Registry Number.
