Check Digit Verification of cas no

The CAS Registry Mumber 33348-72-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,3,4 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 33348-72:
(7*3)+(6*3)+(5*3)+(4*4)+(3*8)+(2*7)+(1*2)=110
110 % 10 = 0
So 33348-72-0 is a valid CAS Registry Number.

Indium(III)-Catalyzed Hydration and Hydroalkoxylation of α,β-Unsaturated Ketones in Aqueous Media

Yun, Jin-Jin,Zhi, Man-Ling,Shi, Wen-Xiao,Chu, Xue-Qiang,Shen, Zhi-Liang,Loh, Teck-Peng

, p. 2632 - 2637 (2018)

The hydration of α,β-unsaturated ketones with water proceeded efficiently in the presence of In(OTf)3 (20 mol%) in aqueous media to afford synthetically versatile β-hydroxyketones in moderate to good yields with good functional group compatibility. The method also can be extended to the hydroalkoxylation of α,β-unsaturated ketones with various alcohols for the efficient synthesis of β-alkoxyketones as well as tetrahydrofuran derivatives. (Figure presented.).

Bismuth trichloride-catalyzed oxy-Michael addition of water and alcohol to α,β-unsaturated ketones

Wu, Zhen,Feng, Xue-Xin,Wang, Qing-Dong,Yun, Jin-Jin,Rao, Weidong,Yang, Jin-Ming,Shen, Zhi-Liang

supporting information, p. 1297 - 1300 (2019/09/30)

An efficient method was developed for the conjugate addition of water to various α,β-unsaturated ketones by using bismuth(III) chloride as a catalyst. The reactions proceeded smoothly in the presence of a catalytic amount of BiCl3 (20 mol%) in aqueous media to furnish a variety of synthetically useful β-hydroxyl ketones in moderate to good yields. Apart from water molecule, various alcohols could also be employed as nucleophiles to react with α,β-unsaturated ketones, leading to β-alkoxyl ketones in modest to high yields. In addition, the mild reaction conditions also entailed the conjugate addition reactions to proceed with the tolerance to a range of functional groups.

Purification and characterization of a (r)-1-phenyl-1, 3-propanediol- producing enzyme from trichosporon fermentans aj-5152 and enzymatic (r)-1-phenyl-1, 3-propanediol production

Kira, Ikuo,Onishi, Norimasa

experimental part, p. 1640 - 1646 (2010/03/24)

An (R)-1-phenyl-1, 3-propanediol-producing enzyme was purified from Trichosporon fermentans AJ-5152. It was NADPH-dependent and converted 3-hydroxy-1- phenylpropane-1-one (HPPO) to (R)-1-phenyl-1, 3-propanediol [(R)-PPD] with anti-Prelog's specificity. It
