70912-53-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70912-53-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,1 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 70912-53:
(7*7)+(6*0)+(5*9)+(4*1)+(3*2)+(2*5)+(1*3)=117
117 % 10 = 7
So 70912-53-7 is a valid CAS Registry Number.

Synthesis of [1,2-A]-fused tricyclic dihydroquinolines by palladiumcatalyzed intramolecular C-N cross-coupling of polarized heterocyclic enamines

Bro?, B?etislav,R??i?ková, Zdeňka,?im?nek, Petr

, p. 118 - 141 (2016/10/22)

A simple methodology for [1,2-A]-fused tricyclic dihydroquinolines is established. The key ste of the methodology is an intramolecular Buchwald-Hartwig amination reaction of suitabl halogenated (both bromo and chloro) cyclic enaminoketones, enaminoesters and enaminonitrile with various ring size (from five-to seven-membered). Optimal reaction conditions (palladiu source, base, ligand) depend on the ring size of the starting enamine, giving 65-98% yield of th tricyclic product. A treatment of the products with perchloric acid gives respective quinoliniu perchlorates.

Synthesis of acetyl-substituted heterocyclic enamines and their reaction with diethyl azodicarboxylate

Cheng,Zhao,Wang,Wang,Huang

, p. 1339 - 1351 (2007/10/02)

Acetyl-substituted heterocyclic enamines 4 were synthesized from lactim ethers 2 and acetylacetone through condensation and deacetylation reactions, and they, along with the ester-substituted heterocyclic enamines 6, reacted with diethyl azodicarboxylate to afford C-adducts 7 and 8 in excellent yields.
