18417-40-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18417-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,1 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 18417-40:
(7*1)+(6*8)+(5*4)+(4*1)+(3*7)+(2*4)+(1*0)=108
108 % 10 = 8
So 18417-40-8 is a valid CAS Registry Number.

1,3-Cycloaddition of nitrile oxides in ionic liquids. An easier route to 3-carboxy isoxazolines, potential constrained glutamic acid analogues

Conti, Dario,Rodriquez, Manuela,Sega, Alessandro,Taddei, Maurizio

, p. 5327 - 5330 (2003)

Several improvements in the cycloaddition of carboethoxyformonitrile oxide (CEFNO) with different alkenes are observed in the ionic liquids [bmim][BF4] and [bmim][PF6]. The possibility of obtaining good yields of the corresponding is

Three-component coupling approach to trachyspic acid

Schmitt, Daniel C.,Lam, Leighann,Johnson, Jeffrey S.

supporting information; experimental part, p. 5136 - 5139 (2011/11/29)

Three-component coupling of the lithium enolate of t-BuOAc, silyl glyoxylate, and an α,β-unsaturated ketone enables the rapid construction of the trachyspic acid carbon skeleton. A 3,4-disubstituted isoxazole is utilized to mask the C7/C9 dicarbonyl. New
