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

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
