Check Digit Verification of cas no

The CAS Registry Mumber 18652-74-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,5 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18652-74:
(7*1)+(6*8)+(5*6)+(4*5)+(3*2)+(2*7)+(1*4)=129
129 % 10 = 9
So 18652-74-9 is a valid CAS Registry Number.

Catalytic enantioselective bromohydroxylation of cinnamyl alcohols

Li, Jing,Shi, Yian

, p. 13040 - 13046 (2021)

This work describes an effective enantioselective bromohydroxylation of cinnamyl alcohols with (DHQD)2PHAL as the catalyst and H2O as the nucleophile, providing a variety of corresponding optically active bromohydrins with up to 95% ee.

Method for synthesizing photoactive bromohydrin compound

-

Paragraph 0106-0111, (2021/07/21)

The invention discloses a method for synthesizing a photoactive bromohydrin compound, which comprises the following steps: reacting cinnamyl alcohol as shown in a formula I, benzamide bromide as shown in a formula II, a quinine derivative, L-camphorsulfonic acid and water in a first organic solvent to obtain the bromohydrin compound as shown in a formula III. According to the method, raw materials are easy to synthesize, reaction conditions are mild, operation is easy and convenient, the yield reaches up to 47%-87%, enantioselectivity can generally reach 80% or above, and the highest point can even reach 95%.

From simple organobromides or olefins to highly value-added bromohydrins: A versatile performance of dimethyl sulfoxide

Song, Song,Huang, Xiaoqiang,Liang, Yu-Feng,Tang, Conghui,Li, Xinwei,Jiao, Ning

supporting information, p. 2727 - 2731 (2015/05/27)

A novel and efficient direct transformation of secondary bromides or olefins to highly value-added bromohydrins has been disclosed. Dimethyl sulfoxide (DMSO), a cheap and common solvent, performs its versatile role as a solvent, an essential oxidant, and also as an oxygen source in this bromohydrin synthesis.
