5900-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5900-33-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,0 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.Calculate Digit Verification of CAS Registry Number 5900-33:
(6*5)+(5*9)+(4*0)+(3*0)+(2*3)+(1*3)=84
84 % 10 = 4
So 5900-33-4 is a valid CAS Registry Number.
