5204-80-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5204-80-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5204-80:
(6*5)+(5*2)+(4*0)+(3*4)+(2*8)+(1*0)=68
68 % 10 = 8
So 5204-80-8 is a valid CAS Registry Number.
