80140-44-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80140-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,1,4 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80140-44:
(7*8)+(6*0)+(5*1)+(4*4)+(3*0)+(2*4)+(1*4)=89
89 % 10 = 9
So 80140-44-9 is a valid CAS Registry Number.
