57193-50-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57193-50-7 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 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 57193-50:
(7*5)+(6*7)+(5*1)+(4*9)+(3*3)+(2*5)+(1*0)=137
137 % 10 = 7
So 57193-50-7 is a valid CAS Registry Number.
