223526-84-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 223526-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,5,2 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 223526-84:
(8*2)+(7*2)+(6*3)+(5*5)+(4*2)+(3*6)+(2*8)+(1*4)=119
119 % 10 = 9
So 223526-84-9 is a valid CAS Registry Number.

Preparation of a 1-unsubstituted-2,3-dihydro-1-benzazepine derivative

Nishiguchi, Atsuko,Ikemoto, Tomomi,Ito, Tatsuya,Miura, Shotaro,Tomimatsu, Kiminori

, p. 1183 - 1192 (2008/02/08)

We developed a three-step method of producing a 1-unsubstituted-2,3-dihydro-1-benzazepine derivative (2) from 11. The alkylation of 9, obtained from 11, and the subsequent intramolecular condensation of 12 in dialkyl carbonate with a metal alcoholate were

, (2012/10/08)

Compounds of the general formula (I): or salts thereof, which exhibit CCR5 antagonism and exert preventive and therapeutic effects against HIV infections: wherein R1 is a 5- to 6-membered aromatic ring which bears a substituent represented by the general formula: R-Z1-X-Z2- (wherein R1 is hydrogen or optionally substituted hydrocarbyl; X is optionally substituted alkylene; and Z1 and Z2 are each a heteroatom) and may be further substituted, with R being optionally bonded to the aromatic ring to form another ring; Y is optionally substituted imino; and R2 and R3 are each optionally substituted aliphatic hydrocarbyl or an optionally substituted hetero-alicyclic group.

An approach to the pyrroloquinoline core of martinelline and martinellic acid

Lovely, Carl J.,Mahmud, Hossen

, p. 2079 - 2082 (2007/10/03)

An expedient method for the assembly of the pyrroloquinoline skeleton found in the martinelline alkaloids using a [3+2] cycloaddition of an azomethine ylide and an alkene has been developed.
