50919-43-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 50919-43-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,9,1 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 50919-43:
(7*5)+(6*0)+(5*9)+(4*1)+(3*9)+(2*4)+(1*3)=122
122 % 10 = 2
So 50919-43-2 is a valid CAS Registry Number.
