Check Digit Verification of cas no

The CAS Registry Mumber 1296133-80-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,6,1,3 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1296133-80:
(9*1)+(8*2)+(7*9)+(6*6)+(5*1)+(4*3)+(3*3)+(2*8)+(1*0)=166
166 % 10 = 6
So 1296133-80-6 is a valid CAS Registry Number.

Enantioselective palladium-catalyzed dearomative cyclization for the efficient synthesis of terpenes and steroids

Du, Kang,Guo, Pan,Chen, Yuan,Cao, Zhen,Tang, Wenjun,Wang, Zheng

, p. 3033 - 3037 (2015)

A novel enantioselective palladium-catalyzed dearomative cyclization has been developed for the efficient construction of a series of chiral phenanthrenone derivatives bearing an all-carbon quaternary center. The effectiveness of this method in the synthe

Paragraph 0099-0104; 0107-0108, (2019/05/08)

The present invention discloses a two-benzo heterocyclic compound, of formula (I) as shown in the structure. Dibenzofluorene and heterocyclic compounds of the LUMO energy level is low, with the electronic transmission material good matching, favorable to electronic injection and transmission. Dibenzofluorene and heterocyclic compound having good hole transmission performance, as luminescent material in the luminescent layer can balance the proportion of electrons and holes, improve the composite probability, make the device light-emitting efficiency is enhanced. Dibenzofluorene and heterocyclic compounds of space configuration can avoid material molecular stacking, and then prevent the intermolecular energy transfer result in high-energy exciton generation, reduce the exciton annihilation, inhibit efficiency roll-off. At the same time, dibenzo heterocyclic compound having good thermal stability, can achieve high-efficiency stable blue-light. The invention also discloses an organic electroluminescent device, at least one functional layer containing the above-mentioned in-diazepine heterocyclic compound, can be obtained with high blue light emitting efficiency and low operating voltage of blue light device.
