4450-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4450-33-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,5 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.Calculate Digit Verification of CAS Registry Number 4450-33:
(6*4)+(5*4)+(4*5)+(3*0)+(2*3)+(1*3)=73
73 % 10 = 3
So 4450-33-3 is a valid CAS Registry Number.
