140145-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140145-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,4 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 140145-73:
(8*1)+(7*4)+(6*0)+(5*1)+(4*4)+(3*5)+(2*7)+(1*3)=89
89 % 10 = 9
So 140145-73-9 is a valid CAS Registry Number.
