74917-81-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74917-81-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,1 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74917-81:
(7*7)+(6*4)+(5*9)+(4*1)+(3*7)+(2*8)+(1*1)=160
160 % 10 = 0
So 74917-81-0 is a valid CAS Registry Number.

Synthesis of 4H-chromene-isoxazole hybrids via ortho-hydroxy directing cyclization of isoxazole-styrenes and Michael addition of imino-chromenes in aqueous medium

Nagaraju, Sakkani,Sathish, Kota,Kashinath, Dhurke

supporting information, p. 1252 - 1258 (2021/03/06)

A green, efficient, and one-pot method synthesis of functionalized 4H-chromene-isoxazole hybrids is reported via o-hydroxy group directing cyclization of isoxazole-styrenes and Michael addition of 3,5-dimethyl-4-nitroisoxazole on 2-imino-2H-chromene-3-carbonitrile (independent methods). The developed methodology was further extended for nitromethane, malononitrile, and alkylcyanoacetates as Michael donors.

A fast and highly efficient protocol for synthesis of pyrrolo[2,3-d] isoxazoles and a new series of novel benzyl bis-pyrrolo[2,3-d]isoxazoles using task-specific ionic liquids as catalyst and green solvent

Rajanarendar, Eligeti,Raju, Samala,Siva Rami Reddy, Atthunuri,Govardhan Reddy, Kundur,Nagi Reddy, Modugu

experimental part, p. 833 - 839 (2010/09/05)

We report a mild, fast, highly efficient and eco-friendly protocol for the green synthesis of pyrrolo[2,3-d]isoxazoles and a new series of novel benzyl bis-pyrrolo[2,3-d]isoxazoles from nitro styrylisoxazoles in SnCl 2-ionic liquid by reductive

Fused Heterocycles. IV. Synthesis of 7-(o-Hydroxyphenyl)-3,5-dimethyl-7,8-dihydro-6H-isoxazoloazepines

Malla Reddi, Kooturu,Janakirama Rao, Citineni,Krishna Murthy, Ananthula

, p. 3617 - 3618 (2007/10/02)

Michael addition of acetylacetone to 3-methyl-4-nitro-5-(o-hydroxystyryl)isoxazoles gives 4-(o-acetoxyphenyl)-5-(3-methyl-4-nitro-5-isoxazoyl)-2-pentanones (4).Reductive cyclization of 4 with tin(II) chloride and concentrated hydrochloric acid leads to 7-
