80401-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80401-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,0 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80401-34:
(7*8)+(6*0)+(5*4)+(4*0)+(3*1)+(2*3)+(1*4)=89
89 % 10 = 9
So 80401-34-9 is a valid CAS Registry Number.
