Check Digit Verification of cas no

The CAS Registry Mumber 70525-38-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,2 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 70525-38:
(7*7)+(6*0)+(5*5)+(4*2)+(3*5)+(2*3)+(1*8)=111
111 % 10 = 1
So 70525-38-1 is a valid CAS Registry Number.

Aryl-Nickel-Catalyzed Benzylic Dehydrogenation of Electron-Deficient Heteroarenes

Zhang, Pengpeng,Huang, David,Newhouse, Timothy R.

, p. 1757 - 1762 (2020/02/04)

This manuscript describes the first practical benzylic dehydrogenation of electron-deficient heteroarenes, including pyridines, pyrazines, pyrimidines, pyridazines, and triazines. This transformation allows for the efficient benzylic oxidation of heteroarenes to afford heterocyclic styrenes by the action of nickel catalysis paired with an unconventional bromothiophene oxidant.

Ruthenium-catalyzed arylation of 2-alkenylpyridines with aryl bromides: Alternative E,Z-selectivity to Mizoroki-Heck reaction

Oi, Shuichi,Sakai, Kaori,Inoue, Yoshio

, p. 4009 - 4011 (2007/10/03)

(Chemical Equation Presented) Regio- and stereoselective arylation of 2-alkenylpyridines with aryl bromides is catalyzed by specific Ru(II)-phosphine complexes affording β-arylated (Z)-2-alkenylpyridines, in which the aryl moiety is introduced cis to the

STEREOSPECIFIC SYNTHESIS OF (E)-ALKENYLPYRIDINES VIA α-SILYL CARBANION

Konakahara, Takeo,Takagi, Yukio

, p. 2073 - 2076 (2007/10/02)

(E)-2-Alkenylpyridines were stereospecifically prepared from 2-(trimethylsilylmethyl)pyridine and the corresponding (E)-aldimines of anilines by an analogous reaction to the Peterson reaction.
