Check Digit Verification of cas no

The CAS Registry Mumber 176541-91-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,5,4 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 176541-91:
(8*1)+(7*7)+(6*6)+(5*5)+(4*4)+(3*1)+(2*9)+(1*1)=156
156 % 10 = 6
So 176541-91-6 is a valid CAS Registry Number.

Low-Temperature Intramolecular [4+2] Cycloaddition of Allenes with Arenes for the Synthesis of Diene Ligands

Hari, Durga Prasad,Pisella, Guillaume,Wodrich, Matthew D.,Tsymbal, Artem V.,Tirani, Farzaneh Fadaei,Scopelliti, Rosario,Waser, Jerome

, p. 5475 - 5481 (2021)

The intramolecular [4+2] cycloaddition between arenes and allenes first reported by Himbert gives rapid access to rigid polycyclic scaffolds. Herein, we report a one-pot oxyalkynylation/cycloaddition reaction proceeding under mild conditions (23–90 °C) an

Ethynylbenziodazolones (EBZ) as Electrophilic Alkynylation Reagents for the Highly Enantioselective Copper-Catalyzed Oxyalkynylation of Diazo Compounds

Hari, Durga Prasad,Schouwey, Lionel,Barber, Verity,Scopelliti, Rosario,Fadaei-Tirani, Farzaneh,Waser, Jerome

supporting information, (2019/05/28)

Ethynylbenziodoxol(on)e (EBX) cyclic hypervalent iodine reagents are now established reagents for the alkynylation of radicals and nucleophiles, yet they present limited possibilities for further structure and reactivity modification. Herein, the first synthesis is reported for the corresponding ethynylbenziodazolone (EBZ) reagents, in which the oxygen atom in the iodoheterocycle is replaced by a nitrogen atom. The substituent on the nitrogen enables further fine-tuning of the reagent structure and reactivity. EBZ reagents are obtained easily from the corresponding benzamides by using a one-step procedure, and display reactivity comparable to that of EBX reagents. In particular, they are applied in an asymmetric copper-catalyzed oxyalkynylation of diazo compounds, which proceeds in high yield and enantioselectivity for a broad range of substituents on the diazo compounds and the alkyne.

Enantioselective Copper-Catalyzed Oxy-Alkynylation of Diazo Compounds

Hari, Durga Prasad,Waser, Jerome

supporting information, p. 8420 - 8423 (2017/07/06)

Enantioselective catalytic methods allowing the addition of both a nucleophile and an electrophile onto diazo compounds give a fast access into important building blocks. Herein, we report the highly enantioselective oxyalkynylation of diazo compounds usi
