137438-51-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137438-51-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,3 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 137438-51:
(8*1)+(7*3)+(6*7)+(5*4)+(4*3)+(3*8)+(2*5)+(1*1)=138
138 % 10 = 8
So 137438-51-8 is a valid CAS Registry Number.

Anti-Markovnikov Hydrofunctionalization of Alkenes: Use of a Benzyl Group as a Traceless Redox-Active Hydrogen Donor

Lonca, Geoffroy Hervé,Ong, Derek Yiren,Tran, Thi Mai Huong,Tejo, Ciputra,Chiba, Shunsuke,Gagosz, Fabien

, p. 11440 - 11444 (2017/09/11)

A protocol for the anti-Markovnikov hydrofunctionalization of alkenes has been developed by the use of a benzyl group as a traceless redox-active hydrogen donor. Under copper catalysis and in the presence of CF3- or N3-containing hyp

Iron-catalysed, general and operationally simple formal hydrogenation using Fe(OTf)3 and NaBH4

MacNair, Alistair J.,Tran, Ming-Ming,Nelson, Jennifer E.,Sloan, G. Usherwood,Ironmonger, Alan,Thomas, Stephen P.

supporting information, p. 5082 - 5088 (2014/07/08)

An operationally simple and environmentally benign formal hydrogenation protocol has been developed using highly abundant iron(iii) salts and an inexpensive, bench stable, stoichiometric reductant, NaBH4, in ethanol, under ambient conditions. This reaction has been applied to the reduction of terminal alkenes (22 examples, up to 95% yield) and nitro-groups (26 examples, up to 95% yield). Deuterium labelling studies indicate that this reaction proceeds via an ionic rather than radical mechanism.

Cesium salt of tungstosilicic acid fabricated by nano-casting strategy: An efficient catalyst for the three-component Hosomi-Sakurai reaction

Fazaeli, Razieh,Aliyan, Hamid,Bagi, Mohammad Javad

experimental part, p. 677 - 688 (2012/06/18)

We have used SBA-15 silicas as hard templates for the nano-fabrication of Cs1.8H2.2SiW12O40 (CsHSiW) salt nanocrystal. The elimination by HF (or NaOH 90 °C) in the silica matrix from the composites occurred by a
