57402-25-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57402-25-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,0 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 57402-25:
(7*5)+(6*7)+(5*4)+(4*0)+(3*2)+(2*2)+(1*5)=112
112 % 10 = 2
So 57402-25-2 is a valid CAS Registry Number.
