57183-43-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57183-43-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,1,8 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 57183-43:
(7*5)+(6*7)+(5*1)+(4*8)+(3*3)+(2*4)+(1*3)=134
134 % 10 = 4
So 57183-43-4 is a valid CAS Registry Number.
