200339-95-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 200339-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,3,3 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 200339-95:
(8*2)+(7*0)+(6*0)+(5*3)+(4*3)+(3*9)+(2*9)+(1*5)=93
93 % 10 = 3
So 200339-95-3 is a valid CAS Registry Number.
