Check Digit Verification of cas no

The CAS Registry Mumber 93961-29-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,9,6 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 93961-29:
(7*9)+(6*3)+(5*9)+(4*6)+(3*1)+(2*2)+(1*9)=166
166 % 10 = 6
So 93961-29-6 is a valid CAS Registry Number.

All-Carbon Tetrasubstituted Olefins Synthesis from Diazo Compounds and Iodonium Ylides under Blue LED Irradiation

Zhao, Yan-Rui,Li, Lei,Xu, Guo-Yong,Xuan, Jun

supporting information, p. 506 - 511 (2021/12/08)

A route for the construction of all-carbon tetra-substituted olefins through visible-light promoted coupling of diazo compounds with iodonium ylides was developed. A wide range of all-carbon tetra-substituted olefins was obtained in moderate to good yields. The synthetic values of the current method were further approved by the synthesis of natural isolates modified alkenes and the successful transformation of final olefins into important heterocycles. (Figure presented.).

Catalyst-free, scalable heterocyclic flow photocyclopropanation

Kl?pfer, Viktor,Eckl, Robert,Flo?, Johannes,Roth, Philippe M. C.,Reiser, Oliver,Barham, Joshua P.

supporting information, p. 6366 - 6372 (2021/09/10)

Industrial process development is driven by several factors, including safety, cost, robustness and environmental aspects. However, attempts to establish aryl diazo esters-which are highly valued in academic research for their reactivity as carbene precur

Tropylium-Catalyzed O-H Insertion Reactions of Diazoalkanes with Carboxylic Acids

Empel, Claire,Nguyen, Thanh Vinh,Koenigs, Rene M.

supporting information, p. 548 - 553 (2021/01/26)

Herein, we describe the application of a nonbenzenoid aromatic carbocation, namely tropylium, as an organic Lewis acid catalyst in O-H functionalization reactions of diazoalkanes with benzoic acids. The newly developed protocol is applicable to a wide range of diazoalkane and carboxylic acid substrates with excellent efficiency (43 examples, up to 99% yield).
