147801-94-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 147801-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,8,0 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 147801-94:
(8*1)+(7*4)+(6*7)+(5*8)+(4*0)+(3*1)+(2*9)+(1*4)=143
143 % 10 = 3
So 147801-94-3 is a valid CAS Registry Number.

Iodine-promoted oxidative conversion of o-vinyl diaryl ketones into o-acetyl diaryl ketones, synthesis of 1-methyl-4-arylphthalazines as analogues of podophyllotoxin

Harikrishna, Kommidi,Mukkamala, Ramesh,Hinkelmann, Bettina,Sasse, Florenz,Aidhen, Indrapal Singh

, p. 1066 - 1075 (2014/03/21)

A new method is described for the metal-free oxidation of o-vinyl diaryl ketones in the presence of molecular iodine or N-iodosuccinimide to give o-acetyl diaryl ketones. This transformation involves the initial formation of an iodohydrin, and the o-carbo

Regioselective quadruple domino aldolization/aldol condensation/Michael/ SNAr-cyclization: Construction of hexacyclic indeno-fused C-nor-D-homo-steroid frameworks

Chanda, Tanmoy,Chowdhury, Sushobhan,Ramulu, B. Janaki,Koley, Suvajit,Jones, Raymond C.F.,Singh, Maya Shankar

, p. 2190 - 2194 (2014/03/21)

An operationally simple and highly atom-economic anionic quadruple domino reaction sequence for the synthesis of hexacyclic indeno-fused naphthalene/quinoline molecules having structural resemblance with the C-nor-D-homo-steroid nucleus has been developed. Promoter and solvent specificity, regioselectivity and mechanistic details were experimentally established. Catalyst concentration and solvent dependent switching of domino steps creating four new C-C bonds are discussed.

Synthesis of 1,2-diacylbenzenes from o-hydroxyaryl ketone acylhydrazones using [(diacetoxy)iodo]benzene

Moriarty,Berglund,Rao

, p. 318 - 321 (2007/10/02)

2'-Hydroxyacetophenone and 2'-hydroxypropiophenone acylhydrazones 3 are oxidized to 1,2-diacylbenzenes 4 using [(diacetoxy)iodo]benzene in dichloromethane at room temperature in a synthetically useful and high yield reaction.
