Check Digit Verification of cas no

The CAS Registry Mumber 22883-27-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,8,8 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 22883-27:
(7*2)+(6*2)+(5*8)+(4*8)+(3*3)+(2*2)+(1*7)=118
118 % 10 = 8
So 22883-27-8 is a valid CAS Registry Number.

A new method for the synthesis of chalcone derivatives promoted by PPh3/I2under non-alkaline conditions

Xue, Kangsheng,Sun, Guoxiang,Zhang, Yanzhi,Chen, Xubing,Zhou, Yang,Hou, Jinjun,Long, Huali,Zhang, Zijia,Lei, Min,Wu, Wanying

, p. 625 - 634 (2021)

A straightforward and general method has been developed for the synthesis of chalcone derivatives by a Claisen-Schmidt reaction in the presence of PPh3/I2 in 1,4-dioxane under reflux temperatures. With the condensation of the aromatic ketone and aldehyde occurring at non-strongly alkaline conditions, our proposed method significantly expands the range of applicable substrates, especially for groups that are unstable under alkaline conditions.

Synthesis, docking, and evaluation of novel thiazoles for potent antidiabetic activity

Sravanthi,Sajitha Lulu,Vino,Jayasri,Mohanapriya,Manju

, p. 1306 - 1315 (2017)

In this study, a series of novel substituted pyrazoles containing indole and thiazole motifs were synthesized and evaluated for their antihyperglycemic activity against α-amylase and α-glucosidase enzymes. Among them, 2-(5-(1H-indol-3-yl)-3-phenyl-1H-pyra

Synthesis and evaluation of chalcone derivatives as novel sunscreen agent

Jumina, Jumina,Lee, Wonkoo,Swasono, Respati Tri,Wijayanti, Lucia Wiwid

, (2021/05/26)

Ultraviolet (UV) irradiation is a serious problem for skin health thus the interest in the research to develop sunscreen agent has been increasing. Chalcone is a promising compound to be developed as its chromophore absorbs in the UV region. Therefore, in
