19775-91-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19775-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,7 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19775-91:
(7*1)+(6*9)+(5*7)+(4*7)+(3*5)+(2*9)+(1*1)=158
158 % 10 = 8
So 19775-91-8 is a valid CAS Registry Number.

Asymmetric transfer hydrogenation of cycloalkyl vinyl ketones to allylic alcohols catalyzed by ruthenium amido complexes

Liu, Sensheng,Cui, Peng,Wang, Juan,Zhou, Haifeng,Liu, Qixing,Lv, Jinliang

, p. 264 - 267 (2019/01/10)

A chemoselective 1,2-reduction of cycloalkyl vinyl ketones via asymmetric transfer hydrogenation is described. The reduction proceeded smoothly with a chiral diamine ruthenium complex as a catalyst and a HCOOH-NEt3 azeotrope as both a hydrogen source and solvent under mild conditions. A wide range of 1-cycloalkyl chiral allylic alcohols were obtained in good yields and up to 87% ee. It was found that the alkyl group plays an important role in the enantioselectivity.

Structure-based optimization of click-based histone deacetylase inhibitors

Hou, Jingli,Feng, Congran,Li, Zhonghua,Fang, Qinghong,Wang, Huihui,Gu, Guoxian,Shi, Yikang,Liu, Pi,Xu, Feng,Yin, Zheng,Shen, Jie,Wang, Peng

supporting information; experimental part, p. 3190 - 3200 (2011/07/29)

Previously, we reported a click-chemistry based approach to the synthesis of a novel class of histone deacetylase (HDAC) inhibitors [1]. The lead compound NSC746457 was found to be as potent as SAHA (Vorinostat). Further optimization of NSC746457 by using
