54079-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54079-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,0,7 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 54079-89:
(7*5)+(6*4)+(5*0)+(4*7)+(3*9)+(2*8)+(1*9)=139
139 % 10 = 9
So 54079-89-9 is a valid CAS Registry Number.
