81387-51-1 Usage
General Description
"DL-LEUCINE (15N)" refers to a stable isotope of the amino acid leucine, in which the nitrogen element is replaced with the 15N isotope. Leucine is a branched-chain amino acid that plays a critical role in protein synthesis and muscle repair. The 15N isotope is often used in metabolic tracing studies to track the fate of ingested nutrients and to study protein turnover in the body. DL-LEUCINE (15N) can be used as a labeled internal standard for mass spectrometry-based quantification of leucine in biological samples, allowing for precise measurements of leucine levels and metabolic processes. Overall, "DL-LEUCINE (15N)" serves as a valuable tool in research aimed at understanding the metabolism and functions of leucine in the body.
Check Digit Verification of cas no
The CAS Registry Mumber 81387-51-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,8 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81387-51:
(7*8)+(6*1)+(5*3)+(4*8)+(3*7)+(2*5)+(1*1)=141
141 % 10 = 1
So 81387-51-1 is a valid CAS Registry Number.
