54207-62-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54207-62-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,2,0 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 54207-62:
(7*5)+(6*4)+(5*2)+(4*0)+(3*7)+(2*6)+(1*2)=104
104 % 10 = 4
So 54207-62-4 is a valid CAS Registry Number.
