200504-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 200504-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,5,0 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 200504-91:
(8*2)+(7*0)+(6*0)+(5*5)+(4*0)+(3*4)+(2*9)+(1*1)=72
72 % 10 = 2
So 200504-91-2 is a valid CAS Registry Number.
