57192-17-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57192-17-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,1,9 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 57192-17:
(7*5)+(6*7)+(5*1)+(4*9)+(3*2)+(2*1)+(1*7)=133
133 % 10 = 3
So 57192-17-3 is a valid CAS Registry Number.
