54167-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54167-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,1,6 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 54167-89:
(7*5)+(6*4)+(5*1)+(4*6)+(3*7)+(2*8)+(1*9)=134
134 % 10 = 4
So 54167-89-4 is a valid CAS Registry Number.
