15523-24-7 Usage

Chemical Properties

white to off-white crystals or crystalline powder

Uses

Sodium tetraethylborate is used as a derivatizing agent for the detection of organotin, lead and mercury compounds by using gas chromatography coupled with various sensitive and selective detection methods, such as atomic absorption spectrometry (AAS), atomic emission spectrometry (AES), pulsed-flame photometric detection (PFPD), and mass spectrometry (MS). It is also used as an alkylating agent.

Check Digit Verification of cas no

The CAS Registry Mumber 15523-24-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,2 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 15523-24:
(7*1)+(6*5)+(5*5)+(4*2)+(3*3)+(2*2)+(1*4)=87
87 % 10 = 7
So 15523-24-7 is a valid CAS Registry Number.
