Check Digit Verification of cas no

The CAS Registry Mumber 13519-16-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,1 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13519-16:
(7*1)+(6*3)+(5*5)+(4*1)+(3*9)+(2*1)+(1*6)=89
89 % 10 = 9
So 13519-16-9 is a valid CAS Registry Number.

Iron-mediated desulphurization approach: synthesis of cyanamides and their conversions

Nannapaneni, Madhavi,Pendem, Venkata Bhavanarushi,Tamminana, Ramana

, (2022/01/12)

The iron-mediated efficient multi-component method has been demonstrated for the synthesis of substituted cyanamides from isothiocyanates under mild reaction conditions. Subsequent nucleophilic addition and desulfurization are involved in this proposed synthetic methodology. All the reactions are rapid, facile, and accomplished at room temperature. A variety of substrates readily underwent the optimized reaction conditions to provide their respective target products in good to excellent yields. Furthermore, we have confirmed that no other by-products could be identified during our experimental reaction process.

SO2F2-Mediated one-pot cascade process for transformation of aldehydes (RCHO) to cyanamides (RNHCN)

Ding, Chengrong,Ge, Shuting,Wei, Junjie,Zhang, Guofu,Zhao, Yiyong

, p. 17288 - 17292 (2020/05/18)

A simple, mild and practical cascade process for the direct conversion of aldehydes to cyanamides was developed featuring a wide substrate scope and great functional group tolerability. This method allows for transformations of readily available, inexpensive, and abundant aldehydes to highly valuable cyanamides in a pot, atom, and step-economical manner with a green nitrogen source. This protocol will serve as a robust tool for the installation of the cyanamide moiety in various complicated molecules.

CF3SO2Na as a Bifunctional Reagent: Electrochemical Trifluoromethylation of Alkenes Accompanied by SO2 Insertion to Access Trifluoromethylated Cyclic N-Sulfonylimines

He, Zeying,Jiao, Lingcong,Li, Zheng,Liao, Wei-Wei,Sun, Yunhai,Wei, Zhonglin

supporting information, p. 7266 - 7270 (2020/03/23)

An unprecedented electrochemical trifluoromethylation/SO2 insertion/cyclization process has been achieved in an undivided cell in an atom-economic fashion. The protocol relies on tandem cyclization of N-cyanamide alkenes by using Langlois’ reagent as a source of both CF3 and SO2 under direct anodically oxidative conditions, in which two C?C bonds, two C?X bonds (N?S and S?C), and two rings were formed in a single operation. This transformation enabled efficient construction of various trifluoromethylated cyclic N-sulfonylimines from readily accessible materials.

A cascade process for directly converting nitriles (RCN) to cyanamides (RNHCN) via SO2F2-activated Tiemann rearrangement

Zhang, Guofu,Zhao, Yiyong,Ding, Chengrong

, p. 7684 - 7688 (2019/08/30)

A simple, mild and practical process for the direct conversion of nitriles to cyanamides was newly discovered and exhibited a wide substrate scope as well as great functional group-tolerability (36 examples). In this efficient strategy, the in situ generated amidoximes obtained from the reaction of nitriles with hydroxylamine subsequently underwent Tiemann rearrangement, producing the corresponding cyanamides with great isolated yields under SO2F2. Additionally, the control experiments reportedly shed light on the tentative mechanism involved in the formation and elimination of the key intermediate: a sulfonyl ester.

Selective Gold-Catalysed Synthesis of Cyanamides and 1-Substituted 1H-Tetrazol-5-Amines from Isocyanides

?koch, Karel,Císa?ová, Ivana,?těpni?ka, Petr

, p. 13788 - 13791 (2018/09/14)

The newly discovered gold-catalysed reaction of isocyanides with hydrazoic acid generated in situ from trimethylsilyl azide and methanol (or, alternatively, from NaN3/AcOH) produces either cyanamides or 1-substituted 1H-tetrazol-5-amines, depending on the amount of available HN3. The reaction proceeds selectively and in generally high yields of either product, thus providing a particularly convenient access to a wide range of substituted 1H-tetrazol-5-amines that are rather difficult to access otherwise.

One-pot three-component tandem reaction: Synthesis of aryl/alkyl cyanamides libraries and their further conversion into tetrazole derivatives

Mandapati, Usharani,Mandapati, Pavan,Pinapati, Srinivasarao,Tamminana, Ramana,Rudraraju, Rameshraju

supporting information, p. 500 - 510 (2018/02/06)

We have developed methodology for the synthesis of aryl/alkyl cyanamides from amines in one-pot four steps reaction using cheap, readily available and air stable copper source as catalyst under mild reaction conditions. We have also studied the application of cyanamides. In this connection, we could construct aryl tetrazolamine from cyanamides using click reaction.

Cobalt-promoted one-pot reaction of isothiocyanates toward the synthesis of aryl/alkylcyanamides and substituted tetrazoles

Seelam, Mohan,Kammela, Prasada Rao,Shaikh, Bajivali,Tamminana, Ramana,Bogiri, Sujatha

, p. 535 - 544 (2018/07/05)

[Figure not available: see fulltext.] The synthesis of cyanamides and tetrazoles from isothiocyanates through tandem reaction using cobalt catalyst has been demonstrated. In the case of tetrazole preparation, the reaction involved addition/desulfurization/nucleophilic addition/electrocyclization, whereas aromatic cyanamides were constructed from isothiocyanates through addition/desulfurization. Cheap cobalt sulfate was used for the synthesis of various cyanamides and tetrazoles. In addition, cobalt catalyst was found to be desulfurization reagent that has not been previously reported. The final products have been obtained from starting precursors in good to high yield.

Synthesis of Diverse Boron-Handled N-Heterocycles via Radical Borylative Cyclization of N-Allylcyanamides

A synthetic method based on radical borylation/cyclization cascades of N-allylcyanamides was developed to construct diverse boron-substituted N-heterocycles. In the reaction process, the N-heterocyclic carbene-boryl radical underwent a chemo- and regiosel

Development of S-Substituted Thioisothioureas as Efficient Hydropersulfide Precursors

Khodade, Vinayak S.,Toscano, John P.

, p. 17333 - 17337 (2019/01/04)

Because of their inherent instability, hydropersulfides (RSSH) must be generated in situ using precursors, but very few physiologically useful RSSH precursors have been developed to date. In this work, we report the design, synthesis, and evaluation of novel S-substituted thiosiothioureas as RSSH precursors. These water-soluble precursors show efficient and controllable release of RSSH under physiological conditions.
