24563-20-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 24563-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,5,6 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 24563-20:
(7*2)+(6*4)+(5*5)+(4*6)+(3*3)+(2*2)+(1*0)=100
100 % 10 = 0
So 24563-20-0 is a valid CAS Registry Number.
