24880-42-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 24880-42-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,8,8 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 24880-42:
(7*2)+(6*4)+(5*8)+(4*8)+(3*0)+(2*4)+(1*2)=120
120 % 10 = 0
So 24880-42-0 is a valid CAS Registry Number.
