57428-70-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57428-70-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,2 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 57428-70:
(7*5)+(6*7)+(5*4)+(4*2)+(3*8)+(2*7)+(1*0)=143
143 % 10 = 3
So 57428-70-3 is a valid CAS Registry Number.
