27702-93-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 27702-93-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,7,0 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 27702-93:
(7*2)+(6*7)+(5*7)+(4*0)+(3*2)+(2*9)+(1*3)=118
118 % 10 = 8
So 27702-93-8 is a valid CAS Registry Number.

Cyanation of N-acylhydrazones with trimethylsilyl cyanide promoted by a Bronsted base and a Lewis acid

Konishi, Hideyuki,Ogawa, Chikako,Sugiura, Masaharu,Kobayashi, Shu

, p. 1899 - 1903 (2007/10/03)

Cyanation of N-acylhydrazones using trimethylsilyl cyanide (TMSCN) proceeded well in the presence of an amine to afford the corresponding α-hydrazinonitriles in high yields. For less reactive substrates, the combined use of an amine and a catalytic amount

Phase-transfer catalyzed addition of hydrogen cyanide to N-substituted hydrazones

Chiba,Okimoto

, p. 209 - 211 (2007/10/02)

In a two-phase system consisting of aqueous sodium cyanide and an inert organic solvent and containing a phase-transfer catalyst, ketone benzoylhydrazones, tosylhydrazones, and methoxycarbonylhydrazones upon addition of acetic acid readily add hydrogen cy
