1256498-60-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1256498-60-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,4,9 and 8 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1256498-60:
(9*1)+(8*2)+(7*5)+(6*6)+(5*4)+(4*9)+(3*8)+(2*6)+(1*0)=188
188 % 10 = 8
So 1256498-60-8 is a valid CAS Registry Number.

Synthesis of Functionalized 1H-Indenes and Benzofulvenes through Iodocyclization of o-(Alkynyl)styrenes

García-García, Patricia,Sanjuán, Ana M.,Rashid, Muhammad A.,Martínez-Cuezva, Alberto,Fernández-Rodríguez, Manuel A.,Rodríguez, Félix,Sanz, Roberto

, p. 1155 - 1165 (2017)

A convenient method for the preparation of synthetically useful 3-iodoindene derivatives has been developed. This protocol, based on the 5-endo iodocyclization reaction of o-(alkynyl)styrenes, represents one of the scarce examples of halocyclizations using olefins as nucleophilic counterparts and allows the synthesis of both 3-iodo-1H-indenes (from β-alkyl-β-alkyl/aryl-o-(alkynyl)styrenes) and 3-iodobenzofulvenes (from β,β-diaryl-o-(alkynyl)styrenes) in good yields under mild reaction conditions. In addition, related alkoxyiodocyclization processes are described, which are particularly interesting in their intramolecular version because they allow the synthesis of heteropolycyclic structures containing the indene core. Finally, the usefulness of the prepared 3-iodoindenes has been demonstrated by the synthesis of several polysubstituted indene derivatives through conventional palladium-catalyzed cross-coupling reactions and iodine-lithium exchange processes.

Halocyclization of o-(alkynyl)styrenes. Synthesis of 3-halo-1H-indenes

Sanz, Roberto,Martinez, Alberto,Garcia-Garcia, Patricia,Fernandez-Rodriguez, Manuel A.,Rashid, Muhammad A.,Rodriguez, Felix

supporting information; experimental part, p. 7427 - 7429 (2010/11/18)

o-(Alkynyl)styrenes undergo halocarbocyclization processes via a 5-endo-dig ring closure. By this strategy an efficient synthesis of 3-halo-1H-indene derivatives has been developed.
