5338-59-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5338-59-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,3 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5338-59:
(6*5)+(5*3)+(4*3)+(3*8)+(2*5)+(1*9)=100
100 % 10 = 0
So 5338-59-0 is a valid CAS Registry Number.
