19859-89-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19859-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,5 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19859-89:
(7*1)+(6*9)+(5*8)+(4*5)+(3*9)+(2*8)+(1*9)=173
173 % 10 = 3
So 19859-89-3 is a valid CAS Registry Number.

The synthesis of methylated epigallocatechin gallate

Lai, Ronghui,Zhao, Wenfang,Huang, Yahui,Zhou, Wen,Wu, Chunlan,Lai, Xingfei,Zhao, Wenxia,Zhang, Ming

, p. 472 - 475 (2015/12/26)

Synthesis of methylated epigallocatechin gallate from (-)-epigallocatechin gallate and propylgallate was accomplished using a benzyl (Bn) group as a protecting group for phenols. This methodology provided (-)-epigallocatechin-3-(4-O-methylgallate), which

Synthesis and PAF antagonist activity of some 2,5-diaryltetrahydrofurans incorporating PAF-like functional groups

Smith,Blackwell,Demaine,Garland,Hodson,Hyde,Parke,Rose,Sawyer,Tilling

, p. 347 - 358 (2007/10/03)

This paper describes the synthesis and structure-activity relationships of a series of 2,5-diaryltetrahydrofurans, as specific and potent antagonists at the rabbit washed platelet activating factor (PAF) receptor. The methoxyl groups in the known PAF antagonist L-652,731 were replaced with functional groups present in PAF and in the 'PAF-like' antagonists. Activity was generally retained or enhanced when one aryl ring in L-652,731 was elaborated; however incorporation of these functional groups into both of the aryl rings greatly reduced or abolished activity. These results are discussed in relation to a putative model for the PAF receptor.
