Check Digit Verification of cas no

The CAS Registry Mumber 671776-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,1,7,7 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 671776-97:
(8*6)+(7*7)+(6*1)+(5*7)+(4*7)+(3*6)+(2*9)+(1*7)=209
209 % 10 = 9
So 671776-97-9 is a valid CAS Registry Number.

The base-free van Leusen reaction of cyclic imines on water: Synthesis of N-fused imidazo 6,11-dihydro β-carboline derivatives

Satyam, Killari,Murugesh,Suresh, Surisetti

, p. 5234 - 5238 (2019/06/07)

Construction of imidazoles has been demonstrated on water under base-free conditions. The reaction of dihydro β-carboline imines and p-toluenesulfonylmethyl isocyanides furnished the corresponding substituted N-fused imidazo 6,11-dihydro β-carboline derivatives in very good yields under ambient conditions. The use of deuterium oxide (D2O) as a solvent enabled the incorporation of deuterium isotopes in the imidazole ring.

Organocatalytic asymmetric synthesis of β-aryl-β-isocyano esters

Morana, Fabio,Basso, Andrea,Bella, Marco,Riva, Renata,Banfi, Luca

, p. 2199 - 2210 (2012/11/07)

The asymmetric addition of malonates to in situ generated N-formylimines of aromatic aldehydes was achieved under phase-transfer catalysis using Cinchona alkaloids-derived quaternary ammonium salts. The resulting β- formamidomalonates have been efficientl
