65838-45-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 65838-45-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,3 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 65838-45:
(7*6)+(6*5)+(5*8)+(4*3)+(3*8)+(2*4)+(1*5)=161
161 % 10 = 1
So 65838-45-1 is a valid CAS Registry Number.

Organocatalysis by a multidentate halogen-bond donor: An alternative to hydrogen-bond based catalysis

Perera, Manomi D.,Aaker?y, Christer B.

supporting information, p. 8311 - 8314 (2019/06/08)

A charge neutral iodoethynyl-based multidentate halogen-bond donor was synthesized and successfully utilized as an organocatalyst in a benchmark Ritter-type solvolysis reaction. The catalytic activity was monitored using 1H NMR spectroscopy and

Synthesis of N,N′-Dialkylated Cyclohexane-1,2-diamines and Their Application as Asymmetric Ligands and Organocatalysts for the Synthesis of Alcohols

Tsygankov, Alexey A.,Chun, Man-Seog,Samoylova, Alexandra D.,Kwon, Seongyeon,Kreschenova, Yuliya M.,Kim, Suhyeon,Shin, Euijin,Oh, Jinho,Strelkova, Tatyana V.,Kolesov, Valerii S.,Zubkov, Fedor I.,Semenov, Sergei E.,Fedyanin, Ivan V.,Chusov, Denis

supporting information, p. 615 - 619 (2017/03/11)

A series of N,N′-dialkylated derivatives of (1R,2R)-cyclohexane-1,2-diamine were synthesized, and a new approach to the one-pot preparation of this type of amine was demonstrated. The prepared diamines were used as organocatalysts for the two-step synthesis of α-hydroxy γ-keto esters from arenes, chlorooxoacetates, and ketones; they were also used as chiral ligands for Meervein-Ponndorf-Verley reductions and Henry reactions.

Preparations of Saturated N-P-N Type Secondary Phosphine Oxides and their Applications in Cross-Coupling Reactions

Chang, Yu-Chang,Liang, Ya-Han,Hong, Fung-E

, p. 353 - 367 (2016/05/09)

A series of cyclohexane-1,2-diamine (3a-3d) and benzene-1,2-diamine derivatives (3e-3h) were pre- pared. Followed by hydrolysis, the reaction of 3a-3c with PCl3 successfully led to the formation of cor- responding metastable saturated heteroato
