57194-41-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57194-41-9 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 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 57194-41:
(7*5)+(6*7)+(5*1)+(4*9)+(3*4)+(2*4)+(1*1)=139
139 % 10 = 9
So 57194-41-9 is a valid CAS Registry Number.
