144303-73-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144303-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,3,0 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144303-73:
(8*1)+(7*4)+(6*4)+(5*3)+(4*0)+(3*3)+(2*7)+(1*3)=101
101 % 10 = 1
So 144303-73-1 is a valid CAS Registry Number.
