70078-14-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70078-14-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,0,7 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 70078-14:
(7*7)+(6*0)+(5*0)+(4*7)+(3*8)+(2*1)+(1*4)=107
107 % 10 = 7
So 70078-14-7 is a valid CAS Registry Number.

Paragraph 0305-0308; 0310-0313; 0315, (2020/01/25)

The invention relates to an alpha-aryl or alkyl substituted borane adduct, a preparation method and applications thereof, specifically to preparation of an alpha-aryl or alkyl substituted borane adduct by carrying out a reaction on hydrazone as an unstabl

Enantioselective Synthesis of Trisubstituted Allenes via Cu(I)-Catalyzed Coupling of Diazoalkanes with Terminal Alkynes

Chu, Wen-Dao,Zhang, Lei,Zhang, Zhikun,Zhou, Qi,Mo, Fanyang,Zhang, Yan,Wang, Jianbo

supporting information, p. 14558 - 14561 (2016/11/18)

A highly enantioselective synthesis of trisubstituted allenes has been achieved through Cu(I)-catalyzed cross-coupling of aryldiazoalkanes and terminal alkynes with chiral bisoxazoline ligands. Alkynyl migratory insertion of Cu(I) carbene is proposed as t

CYCLOADDITIONS OF DISUBSTITUTED DIAZO COMPOUNDS TO P-CHLORO(BISTRIMETHYLSILYL) METHYLENE PHOSPHINE.

Thoraval, J. Y.,Nagai, W.,Yeung Lam Ko, Y. Y. C.,Carrie, R.

, p. 3859 - 3868 (2007/10/02)

Disubstituted diazo compounds rapidly add to P-chloro (bistrimethylsilyl) methylene phosphine at low temperature. 1H, 31P and 13C NMR allow the characterization of the resulting cycloadducts and the establisment of the stereochemistry of the resulting cycloadducts which are potential precursors of ?3λ5 bis methylene phosphorane by nitrogen extrusion.
