20459-36-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20459-36-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,5 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20459-36:
(7*2)+(6*0)+(5*4)+(4*5)+(3*9)+(2*3)+(1*6)=93
93 % 10 = 3
So 20459-36-3 is a valid CAS Registry Number.
