80472-55-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80472-55-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,7 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80472-55:
(7*8)+(6*0)+(5*4)+(4*7)+(3*2)+(2*5)+(1*5)=125
125 % 10 = 5
So 80472-55-5 is a valid CAS Registry Number.
