144193-80-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144193-80-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,1,9 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144193-80:
(8*1)+(7*4)+(6*4)+(5*1)+(4*9)+(3*3)+(2*8)+(1*0)=126
126 % 10 = 6
So 144193-80-6 is a valid CAS Registry Number.
