Check Digit Verification of cas no

The CAS Registry Mumber 22303-76-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,3,0 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 22303-76:
(7*2)+(6*2)+(5*3)+(4*0)+(3*3)+(2*7)+(1*6)=70
70 % 10 = 0
So 22303-76-0 is a valid CAS Registry Number.

Stereoselective Photodimerization of 3-Arylindenones in Solution and in the Solid State

Uemura, Naohiro,Ishikawa, Hiroki,Tamura, Naoki,Yoshida, Yasushi,Mino, Takashi,Kasashima, Yoshio,Sakamoto, Masami

, p. 2256 - 2262 (2018)

Photodimerization of 3-arylindenones in solution and in the solid state was examined. Irradiation of 3-arylindenones in benzene exclusively gave C2-symmetric anti-HH cyclobutane dimers in good yields. In contrast, photolysis in the solid state

Ir-catalyzed asymmetric hydrogenation of 3-arylindenones for the synthesis of chiral 3-arylindanones

Yan, Jun,Nie, Yu,Gao, Feng,Yuan, Qianjia,Xie, Fang,Zhang, Wanbin

supporting information, (2021/02/27)

An efficient synthesis of chiral 3-arylindanones via iridium-catalyzed asymmetric hydrogenation of 3-arylindenones has been developed. The reaction showed good compatibility with various functional groups, delivering a variety of 3-arylindanones in excellent yields and with good enantioselectivities. The reaction was also carried out on a gram-scale, delivering the product in quantitative yield. In addition, the products can be easily derivatized and transformed into natural products and pharmaceutical agents.

Chemistry of 1,3-diarylpropynones in superacids

Vasilyev,Walspurger,Haouas,Sommer,Pale,Rudenko

, p. 3483 - 3489 (2007/10/03)

In superacids with H0 = -14 to -20, it has been found that 1,3-diarylpropynones ArC≡CCOAr′ are either protonated on oxygen of carbonyl groups with the formation of stable ions ArC≡CC(O +H)Ar′ or undergo further transformations when t
