54031-43-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54031-43-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,0,3 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 54031-43:
(7*5)+(6*4)+(5*0)+(4*3)+(3*1)+(2*4)+(1*3)=85
85 % 10 = 5
So 54031-43-5 is a valid CAS Registry Number.
