25319-03-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25319-03-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,3,1 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 25319-03:
(7*2)+(6*5)+(5*3)+(4*1)+(3*9)+(2*0)+(1*3)=93
93 % 10 = 3
So 25319-03-3 is a valid CAS Registry Number.
