19764-87-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19764-87-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,6 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19764-87:
(7*1)+(6*9)+(5*7)+(4*6)+(3*4)+(2*8)+(1*7)=155
155 % 10 = 5
So 19764-87-5 is a valid CAS Registry Number.

Carbenoid reactions of trifluoromethylelement compounds. Part 4. Reactions of trifluoromethylzinc bromide with enamines and methylene bases

Tyrra, Wieland,Naumann, Dieter,Pasenok, Sergej V.,Yagupolskii, Yurii L.

, p. 181 - 186 (1995)

The reactions of ZnBr(CF3)*2CH3CN with 1-morpholinocyclo-pentene and -hexene have been investigated and found to yield mixtures of two isomers of 1-morpholino-1-cyanomethyl-2-difluoromethyl-cyclopentane and -hexane, respectively.The interaction with methylene bases of nitrogen heterocycles leads to the formation of trimethinecyanine dyes.This reaction sequence includes the formation of two carbon-carbon bonds in a one-pot operation.The mechanism of the reaction is discussed. - Keywords: Carbenoid reactions; Trifluoromethylelement compounds; Trifluoromethylzinc bromide; Enamines; Methylene bases; NMR spectroscopy; Mass spectrometry; UV-vis spectroscopy
