638-64-2 Usage
General Description
STEARIC ACID-CARBOXY-14C is a radioactive isotope of stearic acid, a saturated fatty acid commonly found in animal and vegetable fats. This specific isotope, known as carboxy-14C, contains a radioactive carbon-14 atom, which makes it useful for tracing and studying the metabolism and distribution of stearic acid in biological systems. Stearic acid is used in a variety of industrial and cosmetic products, and the labeled isotope can be utilized in research to track the fate of stearic acid in biological processes, such as digestion, absorption, and excretion. Additionally, it can also be used in environmental studies to monitor the fate and transport of stearic acid in ecosystems.
Check Digit Verification of cas no
The CAS Registry Mumber 638-64-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 638-64:
(5*6)+(4*3)+(3*8)+(2*6)+(1*4)=82
82 % 10 = 2
So 638-64-2 is a valid CAS Registry Number.

Synthesis of [14C] acids from their unlabeled counterparts and application toward a novel [14C] labeled hepatitis C virus polymerase inhibitor
Ho, Jonathan Z.,Wallace, Michael A.,Tang, Yui S.,Zhang, Andy S.,Braun, Matthew P.
, p. 251 - 253 (2011/05/02)
A strategy has been developed for the rapid construction of a [ 14C] acid from either an aromatic or an alkyl acid via a decarboxylation-carboxylation sequence. A [14C] labeled heptatitis C virus polymerase inhibitor was prepared. Other examples and the limitations of this methodology are discussed. Copyright
