24011-04-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 24011-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,0,1 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 24011-04:
(7*2)+(6*4)+(5*0)+(4*1)+(3*1)+(2*0)+(1*4)=49
49 % 10 = 9
So 24011-04-9 is a valid CAS Registry Number.
