80554-71-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80554-71-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,5 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 80554-71:
(7*8)+(6*0)+(5*5)+(4*5)+(3*4)+(2*7)+(1*1)=128
128 % 10 = 8
So 80554-71-8 is a valid CAS Registry Number.
