539-20-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 539-20-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.Calculate Digit Verification of CAS Registry Number 539-20:
(5*5)+(4*3)+(3*9)+(2*2)+(1*0)=68
68 % 10 = 8
So 539-20-8 is a valid CAS Registry Number.
