90350-38-2 Usage
General Description
DL-cystine hydrochloride is a chemical compound that is a combination of the amino acid cystine and hydrochloric acid. Cystine is a non-essential amino acid that is crucial for the formation of proteins in the body. It plays a role in the maintenance and repair of tissue, as well as in the production of collagen, which is essential for healthy skin, hair, and nails. The hydrochloride form of cystine is often used as a dietary supplement to support the body's natural production of glutathione, a powerful antioxidant. DL-cystine hydrochloride is also used in the manufacturing of pharmaceuticals, cosmetics, and research applications.
Check Digit Verification of cas no
The CAS Registry Mumber 90350-38-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,5 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90350-38:
(7*9)+(6*0)+(5*3)+(4*5)+(3*0)+(2*3)+(1*8)=112
112 % 10 = 2
So 90350-38-2 is a valid CAS Registry Number.

Palladium-Catalyzed Carbonylative Synthesis of Aryl Selenoesters Using Formic Acid as an Ex Situ CO Source

A new catalytic protocol for the synthesis of selenoesters from aryl iodides and diaryl diselenides has been developed, where formic acid was employed as an efficient, low-cost, and safe substitute for toxic and gaseous CO. This protocol presents a high functional group tolerance, providing access to a large family of selenoesters in high yields (up to 97%) while operating under mild reaction conditions, and avoids the use of selenol which is difficult to manipulate, easily oxidizes, and has a bad odor. Additionally, this method can be efficiently extended to the synthesis of thioesters with moderate-to-excellent yields, by employing for the first time diorganyl disulfides as precursors.
