188685-36-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188685-36-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,6,8 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 188685-36:
(8*1)+(7*8)+(6*8)+(5*6)+(4*8)+(3*5)+(2*3)+(1*6)=201
201 % 10 = 1
So 188685-36-1 is a valid CAS Registry Number.

Synthesis of new type of dendritic molecule and its columnar self-assembly having a potential as molecular cavity

Fu,Nakasugi,Takagawara,Li,Hayakawa,Jikei,Tokita,Kakimoto,Watanabe

, p. 125 - 130 (2005)

In this study, we synthesized the first generation aromatic polyamide dendron having one trioxyethylene chain at the top of the dendron and six octadecyl chains at the other terminals. This material forms two types of crystals, K1 and K2/

Control the self-assembly of fluorenone-based polycatenars by tuning chain length

Zhao, Kai,Xiao, Yulong,Guo, Chunxiang,Chang, Qing,Gao, Hongfei,Cheng, Xiaohong

supporting information, p. 409 - 415 (2019/01/04)

Using Suzuki coupling reactions as key steps, a series of fluorenone-based polycatenars, consisting of a central 2,7-diphenyl-9-fluorenone core connected with the 3,4,5-trialkoxybenzoate unit via –COO- linkage at each side have been synthesized. Upon elon

Liquid-phase RNA synthesis by using alkyl-chain-soluble support

Kim, Shokaku,Matsumoto, Masanori,Chiba, Kazuhiro

supporting information, p. 8615 - 8620 (2013/07/26)

Recent progress in the RNA therapeutics has increased demand for the synthesis of large quantities of oligoribonucleotides. The assembly of RNA oligomers relies mainly on solid-phase approaches. These allow rapid product purification and the ability to drive a target reaction to completion through the use of excess reagents. Despite the known advantages of solid-phase synthesis, some issues in the process remain to be addressed, such as low and limited scale, reagent accessibility, and the use of a very large excess of reagents. Herein, we report a highly efficient and practical method of liquid-phase synthesis of RNA oligomers by using alkyl-chain-soluble support. We demonstrate the utility of the liquid-phase method through 21-mer RNA synthesis on a gram scale. The assembly of RNA oligomers relies principally on solid-phase approaches, although some alternative methods have been developed to date. A highly efficient and practical method of liquid-phase synthesis for RNA oligomers by using an alkyl-chain-type soluble support is reported. The utility of the liquid-phase method through 21-mer RNA synthesis on a gram scale is described (see scheme). Copyright
