132980-49-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 132980-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,8 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 132980-49:
(8*1)+(7*3)+(6*2)+(5*9)+(4*8)+(3*0)+(2*4)+(1*9)=135
135 % 10 = 5
So 132980-49-5 is a valid CAS Registry Number.

Novel Routes to 1-Aryl-1,4-dihydro-3(2H)-isoquinolinones and 2-Substituted or 2,3-Disubstituted Benzofurans by Intramolecular Cyclizations

Katritzky, Alan R.,Lan, Xiangfu,Zhang, Zhongxing

, p. 381 - 387 (2007/10/02)

N-(α-Benzotriazolylalkyl)arylacetamides, readily available from an arylacetamide, an aldehyde and benzotriazole, undergo intramolecular cyclization under acidic conditions to give 1-aryl-1,4-dihydro-3(2H)-isoquinolinones in good to excellent yields.Similarly, 2-(benzotriazol-1-yl)-2-(o-hydroxyphenyl)ethanols, obtained by lithiation of 2-(benzotriazol-1-ylmethyl)phenols followed by quenching with aldehydes or ketones, eliminate a molecule of water and a molecule of benzotriazole yielding 2-substituted and 2,3-disubstituted benzofurans.

o-(α-Benzotriazolylalkyl)phenols: Versatile Intermediates for the Synthesis of Substituted Phenols

Katritzky, Alan R.,Lan, Xiangfu,Lam, Jamshed N.

, p. 1809 - 1817 (2007/10/02)

Phenols and naphthols are benzotriazolylmethylated by 1-(hydroxymethyl)-1H-benzotriazole (13) (a formaldehyde derivative) in the o- or (if both o-positions are occupied) in the p-position.The reaction can be extended to other aldehydes in the case of the naphthols.The methylene group in the o-(benzotriazolylmethyl)phenols can be lithiated (but only after trimethylsilyl protection of the hydroxy group) and then substituted by various electrophiles.The benzotriazole residues in both the primary products and in their substituted derivatives can be displaced by the alkylanions of Grignard reagents or by hydride ions allowing the elaboration of many new types of substituted phenols.
