The chemical compound "C9H10NO4S(1-)*Na(1+)" is a salt formed by the combination of a negatively charged organic molecule, C9H10NO4S(1-), and a positively charged sodium ion, Na(1+). The organic part of the compound, C9H10NO4S(1-), is a sulfonamide derivative, which is characterized by the presence of a sulfonamide group (-SO2NH2) attached to a benzene ring. This type of compound is known for its antibacterial properties and is often used in the synthesis of drugs. The sodium ion, Na(1+), is a common counterion used to neutralize the negative charge of the sulfonamide, making the overall compound neutral and water-soluble. The combination of these two components results in a pharmaceutically relevant salt that can be used in various medical applications, such as treating bacterial infections.

Check Digit Verification of cas no

The CAS Registry Mumber 2894-21-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,9 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2894-21:
(6*2)+(5*8)+(4*9)+(3*4)+(2*2)+(1*1)=105
105 % 10 = 5
So 2894-21-5 is a valid CAS Registry Number.
