20635-13-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20635-13-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,3 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20635-13:
(7*2)+(6*0)+(5*6)+(4*3)+(3*5)+(2*1)+(1*3)=76
76 % 10 = 6
So 20635-13-6 is a valid CAS Registry Number.

Facile microwave-assisted synthesis of thioformamides from isocyanides and carbon disulfide

Abás, Sònia,Moens, Ulrike,Escolano, Carmen

, p. 2768 - 2770 (2017)

A new, fast, solvent-free and efficient method is provided to prepare thioformamides by reacting isocyanides derivatives, carbon disulfide and benzylamine under microwave irradiation.

Chemoselective reduction of isothiocyanates to thioformamides mediated by the Schwartz reagent

De La Vega-Hernández, Karen,Senatore, Raffaele,Miele, Margherita,Urban, Ernst,Holzer, Wolfgang,Pace, Vittorio

supporting information, p. 1970 - 1978 (2019/02/20)

Thioformamides are easily prepared-under full chemocontrol-through the partial reduction of isothiocyanates with the in situ generated Schwartz reagent. The high electrophilicity of the starting materials enables the straightforward addition of the hydride ion, thus constituting a reliable and high-yielding method for obtaining variously functionalized thioformamides. Sensitive chemical groups to the reduction conditions such as nitro, ester, alkene, azo, azide and keto groups do not interfere with the chemoselectivity of the process. Moreover, the stereochemical information embodied in the starting material is fully retained in the final products. The synthetic potential of the selected thioformamide template is also briefly discussed.
