N,N'-BIS(TRIFLUOROACETYL) L-CYSTINE, also known as BTAC, is a synthetic compound that serves as a derivatizing agent in analytical chemistry. It is composed of two molecules of L-cystine, a naturally occurring amino acid, linked together by two trifluoroacetyl groups. BTAC is recognized for its high reactivity and its ability to form stable complexes with biomolecules, which enhances the sensitivity and stability of peptides and proteins during mass spectrometry analysis. Furthermore, it is utilized in the production of pharmaceuticals and as a building block in organic synthesis. Due to its potentially hazardous nature, BTAC requires careful handling and use.

Check Digit Verification of cas no
The CAS Registry Mumber 402-91-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.Calculate Digit Verification of CAS Registry Number 402-91:
(5*4)+(4*0)+(3*2)+(2*9)+(1*1)=45
45 % 10 = 5
So 402-91-5 is a valid CAS Registry Number.
