57018-83-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57018-83-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,0,1 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 57018-83:
(7*5)+(6*7)+(5*0)+(4*1)+(3*8)+(2*8)+(1*3)=124
124 % 10 = 4
So 57018-83-4 is a valid CAS Registry Number.
