57228-29-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57228-29-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,2 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 57228-29:
(7*5)+(6*7)+(5*2)+(4*2)+(3*8)+(2*2)+(1*9)=132
132 % 10 = 2
So 57228-29-2 is a valid CAS Registry Number.
