144193-74-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144193-74-8 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, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 144193-74:
(8*1)+(7*4)+(6*4)+(5*1)+(4*9)+(3*3)+(2*7)+(1*4)=128
128 % 10 = 8
So 144193-74-8 is a valid CAS Registry Number.
