148527-35-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 148527-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,5,2 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 148527-35:
(8*1)+(7*4)+(6*8)+(5*5)+(4*2)+(3*7)+(2*3)+(1*5)=149
149 % 10 = 9
So 148527-35-9 is a valid CAS Registry Number.

A Highly Chemoselective Reduction of Conjugated Nitro Olefins with Hantzsch Ester in the Presence of Silica Gel

FUJI, Masayuki

, p. 4029 - 4036 (1988)

An effective system to reduce conjugated nitro olefins into the corresponding nitroalkanes is described.The system composed Hantzsch ester (HEH) and silica gel in benzene exerts high yield and excellent chemoselectivity under almost neutral conditions.Facile applications of the system to the syntheses of natural products are also described.

Inter- and Intramolecular Cycloadditions of Nitroalkenes with Olefins. 2-Nitrostyrenes

Denmark, Scott E.,Kesler, Brenda S.,Moon, Young-Choon

, p. 4912 - 4924 (2007/10/02)

Aromatic nitroalkenes 9 - 12 underwent Lewis acid catalyzed cycloadditions with various cyclic alkenes to afford high yields of nitronates 25 - 30 with exclusive anti selectivity.Hammett studies helped to further delineate the role of the Lewis acid.Reaction of nitroalkenes 8 and 10 with various cyclic dienes in the presence of a Lewis acid demonstrated the ability of nitroalkenes to behave as dienes in cycloadditions.The major products were the syn diastereomers which arise from an endo-folded transition structure.Finally, intramolecular cycloaddition of 36 - 39 allowed a correlation between the stereochemical course of the reaction and positions of sp2 centers in the tether to be addressed.
