57559-43-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57559-43-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,5,5 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 57559-43:
(7*5)+(6*7)+(5*5)+(4*5)+(3*9)+(2*4)+(1*3)=160
160 % 10 = 0
So 57559-43-0 is a valid CAS Registry Number.
