138371-54-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138371-54-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,7 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138371-54:
(8*1)+(7*3)+(6*8)+(5*3)+(4*7)+(3*1)+(2*5)+(1*4)=137
137 % 10 = 7
So 138371-54-7 is a valid CAS Registry Number.

Direct Conversion of Carboxylic Acids to Alkyl Ketones

Amani, Javad,Molander, Gary A.

, p. 3612 - 3615 (2017/07/15)

An efficient and mild method for acyl-Csp3 bond formation based on the direct conversion of carboxylic acids has been established. This protocol is enabled by the synergistic, Ir-photoredox/nickel catalytic cross-coupling of in situ activated c

Fragment Couplings via CO2 Extrusion-Recombination: Expansion of a Classic Bond-Forming Strategy via Metallaphotoredox

Le, C. Chip,MacMillan, David W. C.

supporting information, p. 11938 - 11941 (2015/10/06)

In this study we demonstrate that molecular fragments, which can be readily coupled via a simple, in situ RO-C=OR bond-forming reaction, can subsequently undergo metal insertion-decarboxylation-recombination to generate Csp2-Csp3 bonds when subjected to metallaphotoredox catalysis. In this embodiment the conversion of a wide variety of mixed anhydrides (formed in situ from carboxylic acids and acyl chlorides) to fragment-coupled ketones is accomplished in good to high yield. A three-step synthesis of the medicinal agent edivoxetine is also described using this new decarboxylation-recombination protocol.
