54720-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54720-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,7,2 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 54720-57:
(7*5)+(6*4)+(5*7)+(4*2)+(3*0)+(2*5)+(1*7)=119
119 % 10 = 9
So 54720-57-9 is a valid CAS Registry Number.
