6894-87-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6894-87-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,9 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6894-87:
(6*6)+(5*8)+(4*9)+(3*4)+(2*8)+(1*7)=147
147 % 10 = 7
So 6894-87-7 is a valid CAS Registry Number.

Palladium-catalyzed cross-coupling of benzyl ketones and α,β- unsaturated carbonyl and phenolic compounds with o-dibromobenzenes to produce cyclic products

Terao, Yoshito,Satoh, Tetsuya,Miura, Masahiro,Nomura, Masakatsu

, p. 2345 - 2350 (2007/10/03)

A number of carbonyl and phenolic compounds efficiently couple with o- dibromobenzenes in the presence of a palladium catalyst and a base to give the corresponding oxygen-containing heterocycles or carbocyclic compounds. Thus, from the reactions of benzyl phenyl ketones, 1-naphthols, and α,β- unsaturated aldehydes and ketones, benzofuran, benzopyran, benzocyclobutane, and indene derivatives, respectively, are produced selectively via the successive formation of C-C and C-O bonds or of two C-C bonds.
