500206-28-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 500206-28-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,2,0 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 500206-28:
(8*5)+(7*0)+(6*0)+(5*2)+(4*0)+(3*6)+(2*2)+(1*8)=80
80 % 10 = 0
So 500206-28-0 is a valid CAS Registry Number.
