144140-43-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144140-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,1,4 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144140-43:
(8*1)+(7*4)+(6*4)+(5*1)+(4*4)+(3*0)+(2*4)+(1*3)=92
92 % 10 = 2
So 144140-43-2 is a valid CAS Registry Number.
