138116-09-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138116-09-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,1,1 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138116-09:
(8*1)+(7*3)+(6*8)+(5*1)+(4*1)+(3*6)+(2*0)+(1*9)=113
113 % 10 = 3
So 138116-09-3 is a valid CAS Registry Number.

Development of 6-arylcoumarins as nonsteroidal progesterone antagonists. Structure–activity relationships and fluorescence properties

Kinoshita, Marie,Negishi, Mai,Sakai, Haruka,Hirano, Tomoya,Mori, Shuichi,Fujii, Shinya,Kagechika, Hiroyuki,Tanatani, Aya

, p. 5602 - 5610 (2016)

Progesterone is involved in multiple physiological processes, including female reproduction, via binding to the progesterone receptor (PR). We have developed 6-arylcoumarins such as 5 and 6 as non-steroidal PR antagonists with receptor-binding-dependent f

Copper(I)-catalyzed hydroalkoxylation/hydrogen-bonding-induced asymmetric hetero-diels-alder cycloaddition cascade: An approach to aromatic spiroketals

Li, Xin,Xue, Jijun,Huang, Chusheng,Li, Ying

supporting information; experimental part, p. 903 - 906 (2012/07/03)

One thing leads to another: Bis(benzannelated) 5,6-spiroketal skeletons can be constructed by an efficient cascade process involving an unprecedented CuI-catalyzed intramolecular alkyne hydroalkoxylation and an asymmetric hetero-Diels-Alder cyc

Convenient synthesis of a simple coumarin from salicylaldehyde and wittig reagent. IV: Improved synthetic method of substituted coumarins

Takeuchi, Yasuo,Ueda, Norihiro,Uesugi, Koji,Abe, Hitoshi,Nishioka, Hiromi,Harayama, Takashi

, p. 217 - 224 (2007/10/03)

The reaction of salicylaldehydes (2) with Horner-Wadsworth-Emmons (HWE) or Ando-HWE reagents was attempted to afford intramolecular phosphonate derivatives (6). A new synthetic method for coumarins (1) was achieved by using protected 2.
