Tetrahydrofuran-3,3,4,4-D4, also known as perdeuterated tetrahydrofuran, is a stable isotope-labeled compound used as an internal standard in various analytical techniques, such as mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy. This chemical is a deuterated version of tetrahydrofuran (THF), a cyclic ether commonly used as a solvent in organic chemistry. The presence of deuterium atoms (D) in place of hydrogen atoms (H) in the molecule allows for better differentiation and quantification of the target analytes in complex mixtures. Tetrahydrofuran-3,3,4,4-D4 is particularly useful in studying the metabolism and pharmacokinetics of drugs, as well as in environmental and industrial applications where precise measurements are required.

2717-68-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2717-68-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,1 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2717-68:
(6*2)+(5*7)+(4*1)+(3*7)+(2*6)+(1*8)=92
92 % 10 = 2
So 2717-68-2 is a valid CAS Registry Number.
