Check Digit Verification of cas no

The CAS Registry Mumber 104293-36-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,9 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 104293-36:
(8*1)+(7*0)+(6*4)+(5*2)+(4*9)+(3*3)+(2*3)+(1*6)=99
99 % 10 = 9
So 104293-36-9 is a valid CAS Registry Number.

Visible-Light Photoredox Alkylation of Heteroaromatic Bases Using Ethyl Acetate as Alkylating Agent

Gy?rfi, Nándor,Kotschy, András,Gyuris, Márió

, p. 6447 - 6454 (2020)

An efficient room-temperature visible-light photoredox α-acyloxyalkylation reaction of N-heteroarenes is reported, which relies on the use of ethyl acetate as a cheap and non-conventional radical source. The direct C(sp2)-C(sp3) coupling was extended to a diverse set of mono-, bi-, and tricyclic of N-heteroaromatics, and the optimized photoredox protocol was successfully performed on a multigram scale. The scope of the alkylating agent was also explored and a plausible mechanism was proposed, involving photoinduced single-electron transfer and hydrogen-atom transfer processes.

FACILE RADICAL DECARBOXYLATIVE ALKYLATION OF HETEROAROMATIC BASES USING CARBOXYLIC ACIDS AND TRIVALENT IODINE COMPOUNDS

Togo, Hideo,Aoki, Masahiko,Yokoyama, Masataka

, p. 6559 - 6562 (2007/10/02)

Many kinds of heteroaromatic bases were easily alkylated by the reaction of carboxylic acids with benzene or pentafluorobenzene via radical decarboxylative pathways.This system was further applied to the reaction with tetrahydrofurylcarboxylic acid, 1-(2,3,5-tri-O-benzyl)-D-ribofuranosylacetic acid, and 1-(2,3,5-tri-O-benzyl)-D-ribofuranosylcarboxylic acid for the model synthesis of C-nucleosides.
