Check Digit Verification of cas no

The CAS Registry Mumber 40141-09-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,4 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40141-09:
(7*4)+(6*0)+(5*1)+(4*4)+(3*1)+(2*0)+(1*9)=61
61 % 10 = 1
So 40141-09-1 is a valid CAS Registry Number.

A Change from Kinetic to Thermodynamic Control Enables trans-Selective Stereochemical Editing of Vicinal Diols

Gu, Xin,Wendlandt, Alison E.,Zhang, Yu-An

supporting information, p. 599 - 605 (2022/01/03)

Here, we report the selective, catalytic isomerization of cis-1,2-diols to trans-diequatorial-1,2-diols. The method employs triphenylsilanethiol (Ph3SiSH) as a catalyst and proceeds under mild conditions in the presence of a photoredox catalyst and under

Preparation of Functionalized Diorganomagnesium Reagents in Toluene via Bromine or Iodine/Magnesium-Exchange Reactions

Desaintjean, Alexandre,Danton, Fanny,Knochel, Paul

supporting information, p. 4461 - 4476 (2021/08/13)

A wide range of polyfunctionalized di(hetero)aryl- and dialkenyl-magnesium reagents are prepared in toluene within 10 to 120 minutes between 78 C and 25 C via an I/Mg- or Br/Mg-exchange reaction using reagents of the general formula R2Mg (R = sBu, Mes). Highly sensitive functional groups, such as triazene or nitro, are tolerated in these exchange reactions, enabling the synthesis of various functionalized (hetero)arene and alkene derivatives after quenching with several electrophiles including allyl bromides, acyl chlorides, aldehydes, ketones, and aryl iodides.

Sulfur-mediated allylic C-H arylation, epoxidation, and aziridination

Luo, Hang,Hu, Gang,Li, Pingfan

, p. 10569 - 10578 (2019/09/30)

Transition-metal-free, sulfur-mediated allylic C-H arylation, epoxidation, and aziridination were realized through one-pot procedures. The reaction design involved initial addition between olefins and triflic anhydride activated sulfoxides, followed by subsequent reactions of the allylic sulfur ylides generated under basic conditions with arylboronic acids, aldehydes, or aldimines, to give allylic arylation, epoxidation, or aziridination products, respectively.
