24423-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 24423-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,4,2 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 24423-91:
(7*2)+(6*4)+(5*4)+(4*2)+(3*3)+(2*9)+(1*1)=94
94 % 10 = 4
So 24423-91-4 is a valid CAS Registry Number.
