408526-05-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 408526-05-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,8,5,2 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 408526-05:
(8*4)+(7*0)+(6*8)+(5*5)+(4*2)+(3*6)+(2*0)+(1*5)=136
136 % 10 = 6
So 408526-05-6 is a valid CAS Registry Number.

A metal-free tandem dehydrogenative α-arylation reaction of propargylic alcohols with 2-alkynylbenzaldoximes toward the synthesis of α-(4-bromo-isoquinolin-1-yl)-propenone skeletons

Abbasi Kejani, Alireza,Alatat, Khalil,Balalaie, Saeed,Bijanzadeh, Hamid Reza,Nikbakht, Ali

supporting information, p. 579 - 583 (2022/02/01)

A tandem reaction of 2-alkynylbenzaldoximes with propargylic alcohols has been developed for the synthesis of α-(4-bromo-isoquinolin-1-yl)-propenones. Employing 2-alkynylbenzaldoximes as a precursor in the presence of Br2 generates 4-bromo-isoquinoline-N-

Lewis Acid-Catalyzed Formal [3+3] Annulation of Propargylic Alcohols with 4-Hydroxy-2H-chromen-2-ones

Han, Ya-Ping,Li, Xue-Song,Li, Ming,Zhu, Xin-Yu,Liang, Yong-Min

supporting information, p. 2796 - 2800 (2018/08/17)

A Lewis acid-catalyzed formal [3+3] cascade annulation strategy for the formation of diverse tricyclic compounds possessing functionalized pyrano[3,2-c]chromen-5(2H)-one fragments has been developed using propargylic alcohols and 4-hydroxy-2H-chromen-2-on

Transition-Metal-Free, Br?nsted Acid-Mediated Cascade Sequence in the Reaction of Propargyl Alcohols with Sulfonamido-indoles/-indolines: Highly Substituted δ- And α-Carbolines

Selvaraj, Karuppu,Swamy, K. C. Kumara

supporting information, p. 15043 - 15056 (2019/01/04)

Br?nsted acid-mediated, transition-metal-free reaction of propargyl alcohols with sulfonamido-indoles/-indolines under mild conditions affords highly substituted δ- or α-carbolines in good to excellent yields. This protocol involves cascade reaction seque
