Check Digit Verification of cas no

The CAS Registry Mumber 25299-49-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,2,9 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 25299-49:
(7*2)+(6*5)+(5*2)+(4*9)+(3*9)+(2*4)+(1*9)=134
134 % 10 = 4
So 25299-49-4 is a valid CAS Registry Number.

DMAP-Catalyzed Reaction of Diethyl 1,3-Acetonedicarboxylate with 2-Hydroxybenzylideneindenediones: Facile Synthesis of Fluorenone-Fused Coumarins

Shkoor, Mohanad,Bayari, Raghad

, p. 795 - 799 (2021/03/01)

The base-catalyzed reaction of diethyl 1,3-acetonedicarboxylate with 2-hydroxybenzylidene indenediones was studied. The reaction provides a facile and expeditious protocol for the synthesis of natural product inspired fluorenone-fused coumarins in good to

Diversity-oriented synthesis of chromenopyrrolidines from azomethine ylides and 2-hydroxybenzylidene indandiones via base-controlled regiodivergent (3+2) cycloaddition

Yu, Jhen-Kuei,Chien, Han-Wei,Lin, Yi-Jung,Karanam, Praneeth,Chen, Yu-Heng,Lin, Wenwei

supporting information, p. 9921 - 9924 (2018/09/11)

An organobase-directed, regiodivergent 1,3-dipolar cycloaddition of azomethine ylides and 2-hydoxybenzylidene indandiones is reported. The scarcely explored reversal of the nucleophilic site in azomethine ylides has been exploited for their regiodivergent (3+2) cycloaddition, which subsequently resulted in two different cascade processes to generate functionally distinct chromenopyrrolidines in a diversity oriented manner.

Benzylidine indane-1,3-diones: As novel urease inhibitors; synthesis, in vitro, and in silico studies

Bano, Bilquees,Kanwal,Khan, Khalid Mohammed,Begum, Farida,Lodhi, Muhammad Arif,Salar, Uzma,Khalil, Ruqaiya,Ul-Haq, Zaheer,Perveen, Shahnaz

, p. 658 - 671 (2018/09/29)

Current study deals with the evaluation of indane-1,3-dione based compounds as new class of urease inhibitors. For that purpose, benzylidine indane-1,3-diones (1–30) were synthesized and fully characterized by different spectroscopic techniques including
