80311-43-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80311-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,1 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80311-43:
(7*8)+(6*0)+(5*3)+(4*1)+(3*1)+(2*4)+(1*3)=89
89 % 10 = 9
So 80311-43-9 is a valid CAS Registry Number.
