Check Digit Verification of cas no

The CAS Registry Mumber 41963-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,9,6 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 41963-20:
116 % 10 = 6
So 41963-20-6 is a valid CAS Registry Number.

NHC-catalyzed silylative dehydration of primary amides to nitriles at room temperature

Ahmed, Jasimuddin,Hota, Pradip Kumar,Maji, Subir,Mandal, Swadhin K.,Rajendran, N. M.

supporting information, p. 575 - 578 (2020/01/29)

Herein we report an abnormal N-heterocyclic carbene catalyzed dehydration of primary amides in the presence of a silane. This process bypasses the energy demanding 1,2-siloxane elimination step usually required for metal/silane catalyzed reactions. A detailed mechanistic cycle of this process has been proposed based on experimental evidence along with computational study.

The application of NCTS (N-cyano-N-phenyl-p-toluenesulfonamide) in palladium-catalyzed cyanation of arenediazonium tetrafluoroborates and aryl halides

Li, Jizhen,Xu, Wenbin,Ding, Junshuai,Lee, Kuo-Hsiung

supporting information, p. 1205 - 1209 (2016/03/01)

Using NCTS (N-cyano-N-phenyl-p-toluenesulfonamide) as an electrophilic cyanation reagent, palladium-catalyzed cyanation of arenediazonium tetrafluoroborates and aryl halides was achieved under mild conditions. The method allowed the effective synthesis of various aryl nitriles in suitable yields via a coupling reaction.

Catalytic Sandmeyer cyanation as a synthetic pathway to aryl nitriles

Beletskaya, Irina P.,Sigeev, Alexander S.,Peregudov, Alexander S.,Petrovskii, Pavel V.

, p. 3810 - 3812 (2007/10/03)

The catalytic version of Sandmeyer reaction for a number of aryl diazonium salts was investigated. Aryl nitriles ArCN were obtained by the Cu(I)/Cu(II) catalyzed reactions of aryl diazonium salts with KCN in good yields. The reactions with diazonium salts with electron-withdrawing groups led to formation of a corresponding nitrile in a high yield. The yield was found to be lower for the compounds containing electron-donating groups.
