80404-57-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80404-57-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,0 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80404-57:
(7*8)+(6*0)+(5*4)+(4*0)+(3*4)+(2*5)+(1*7)=105
105 % 10 = 5
So 80404-57-5 is a valid CAS Registry Number.
