53333-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53333-55-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,3,3 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 53333-55:
(7*5)+(6*3)+(5*3)+(4*3)+(3*3)+(2*5)+(1*5)=104
104 % 10 = 4
So 53333-55-4 is a valid CAS Registry Number.
