Biochem/physiol Actions
L-Cystine is a natural proteinogenic amino acid sulfide dimer of L-cysteine. L-cystine is used as a cell culture supplement. L-cystine is also used to characterize and identify specific amino acid transport systems in cells such as system system Xc(─) .
Check Digit Verification of cas no
The CAS Registry Mumber 30925-07-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,9,2 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 30925-07:
(7*3)+(6*0)+(5*9)+(4*2)+(3*5)+(2*0)+(1*7)=96
96 % 10 = 6
So 30925-07-6 is a valid CAS Registry Number.

Palladium-Catalyzed Carbonylative Synthesis of Aryl Selenoesters Using Formic Acid as an Ex Situ CO Source
Alves, Diego,Sacramento, Manoela Do,Santi, Claudio,Schwab, Ricardo S.,Teixeira, Wystan K. O.,Yano De Albuquerque, Danilo

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.
