3850-45-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3850-45-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,5 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3850-45:
(6*3)+(5*8)+(4*5)+(3*0)+(2*4)+(1*5)=91
91 % 10 = 1
So 3850-45-1 is a valid CAS Registry Number.

Solar and Visible Light Assisted Peptide Coupling

Amino acid and peptide couplings are widely used in fields related to pharma and materials. Still, current peptide synthesis continues to rely on the use of expensive, water sensitive, and waste-generating coupling reagents, which are often prepared in mu

4-(4,6-Dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium Toluene-4-sulfonate (DMT/NMM/TsO?) Universal Coupling Reagent for Synthesis in Solution

Fraczyk, Justyna,Kaminski, Zbigniew J.,Katarzynska, Joanna,Kolesinska, Beata

, (2018/01/27)

4-(4,6-Dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium toluene-4-sulfonate (DMT/NMM/TsO?), a representative member of the inexpensive and environmentally-friendly N-triazinylammonium family of sulfonates, has been found to be a very effective coupling reagent for the synthesis of amides, esters and peptides in solution. This study confirms the usefulness of DMT/NMM/TsO? for peptide synthesis in solution, starting from Z-, Fmoc-, and Boc-protected substrates as well as unnatural building blocks. Peptide synthesis with DMT/NMM/TsO? produced high yields, with high crude product purity and low risk of racemization. In all cases, stoichiometric amounts of reagents were used and the standard synthetic procedure, without the need for time-consuming optimization stages or expensive chromatographic purification. DMT/NMM/TsO? was also found to be very useful for the synthesis of oligopeptides using a fragment coupling strategy.

Phosphorus oxychloride as an efficient coupling reagent for the synthesis of esters, amides and peptides under mild conditions

Chen, Hu,Xu, Xunfu,Liu, Liu,Tang, Guo,Zhao, Yufen

, p. 16247 - 16250 (2013/09/23)

A mild method is described for the conversion of carboxylic acids into esters, amides, as well as peptides without racemization through carboxyl activation by the reagent combination of POCl3 and DMAP. Long chain alcohols could be converted to the corresponding ester in good yields. 31P NMR spectrum was used to detect phosphorus-containing intermediates in ongoing reactions directly, and a possible mechanism has been proposed based on these results.
