5004-80-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5004-80-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,0 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5004-80:
(6*5)+(5*0)+(4*0)+(3*4)+(2*8)+(1*0)=58
58 % 10 = 8
So 5004-80-8 is a valid CAS Registry Number.
