Check Digit Verification of cas no

The CAS Registry Mumber 24517-59-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,5,1 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 24517-59:
(7*2)+(6*4)+(5*5)+(4*1)+(3*7)+(2*5)+(1*9)=107
107 % 10 = 7
So 24517-59-7 is a valid CAS Registry Number.

Cooperative Light-Activated Iodine and Photoredox Catalysis for the Amination of Csp3 ?H Bonds

Becker, Peter,Duhamel, Thomas,Stein, Christopher J.,Reiher, Markus,Mu?iz, Kilian

, p. 8004 - 8008 (2017)

An unprecedented method that makes use of the cooperative interplay between molecular iodine and photoredox catalysis has been developed for dual light-activated intramolecular benzylic C?H amination. Iodine serves as the catalyst for the formation of a n

Bis(trifluoromethanesulfonimide) (BSI): Acidity and application to hydrofunctionalization as a Br?nsted acid catalyst

Takagi, Ryukichi,Sakai, Yuichiro,Duong, Duyen Thi

, (2021/03/23)

A binaphthyl derivative, bearing bis(trifluoromethanesulfonimide) (BSI) moiety, was developed as a novel Br?nsted acid. Computational prediction of the pKa value of BSI indicated its classification as a strong Br?nsted acid. BSI catalyzed the h

Visible light bromide catalysis for oxazoline, pyrrolidine, and dihydrooxazine synthesesviaCsp3-H functionalizations

Kaur, Navdeep,Ziegelmeyer, Elizabeth C.,Farinde, Olutayo N.,Truong, Jonathon T.,Huynh, Michelle M.,Li, Wei

supporting information, p. 10387 - 10390 (2021/10/14)

A catalytic benzylic Csp3-H functionalization protocol is described here. This visible light-mediated process is centered on the utilization of a bromide catalyst and oxidant to generate a nitrogen (N)-centered radical for a site-selective hydrogen atom transfer (HAT) process. This strategy enabled the unconventional syntheses of a number of N-heterocycles dependent on the amide identity. We also discovered a nucleophilicity-dependent kinetic resolution for stereochemical differentiation of Csp3-H bonds that enabled the stereoselective synthesis ofcis- andtrans-oxazolines.
