Check Digit Verification of cas no

The CAS Registry Mumber 6771-54-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,7 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6771-54:
(6*6)+(5*7)+(4*7)+(3*1)+(2*5)+(1*4)=116
116 % 10 = 6
So 6771-54-6 is a valid CAS Registry Number.

Programmed Sequential Additions to Halogenated Mucononitriles

Zahara, Adam J.,Hinds, Elsa M.,Nguyen, Andrew L.,Wilkerson-Hill, Sidney M.

supporting information, p. 8065 - 8069 (2020/11/02)

Dihalomucononitriles were synthesized and their reactivity evaluated to assess their ability to function as linchpin reagents. Bis(2-chloroacrylonitrile) and bis(2-bromoacrylonitrile) were synthesized from 2,1,3-benzothiadiazole and undergo conjugate addition/elimination reactions with both nitrogen (40-95% yield) and carbon nucleophiles (72-93% yield). Secondary amines undergo monosubstitutions, while carbon nucleophiles are added twice. The sequence of addition of the nucleophiles could be controlled to give mixed addition products. The multicomponent coupling products could then be converted to natural product like motifs using intramolecular cyclization reactions.

Metal free biomimetic deaminative direct C-C coupling of unprotected primary amines with active methylene compounds

Ghosh, Santanu,Jana, Chandan K.

supporting information, p. 10153 - 10157 (2019/12/26)

An unprecedented direct C-C coupling reaction of unprotected primary amines with active methylene compounds is reported. The reaction involves a biomimetic deamination of amines which was achieved under conditions free of metallic reagents and strong oxidizing agents. A wide range of primary amines was reacted with different active methylene compounds to provide structurally diverse trisubstituted alkenes and dihydropyridines. A kinetic study revealed an activation barrier of 10.1 kcal mol-1 for the conversion of a key intermediate of the reaction.

Lipase-Catalysed Addition of Pyrrolidine to Chalcone and Benzylidene Malonate Derivatives

Habibi,Yousefi,Kheyrabadi,Mohammadi,Moemeni,Nazari

, p. 861 - 864 (2015/12/26)

The porcine pancreas lipase (PPL) type II catalyzes the aminolysis of benzylidene malonates by regiospecific amidation of substrates and afforded the Z-isomer; no E-isomer or diamide byproducts were observed. PPL also catalyzes Michael addition of acetophenone to various derivatives of chalcones.
