Check Digit Verification of cas no

The CAS Registry Mumber 809274-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,9,2,7 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 809274-63:
(8*8)+(7*0)+(6*9)+(5*2)+(4*7)+(3*4)+(2*6)+(1*3)=183
183 % 10 = 3
So 809274-63-3 is a valid CAS Registry Number.

Synthesis of Multibromo-Substituted Quinolines by NBS-Mediated Cascade Electrophilic Bromination/Cyclization of N -(3-Phenylprop-2-ynyl)anilines

Deng, Si,Ouyang, Wenliang,Bai, Jiang,Song, Xian-Rong,Yang, Ruchun,Xiao, Qiang

, p. 2469 - 2476 (2021)

A new and convenient protocol is presented here for the synthesis of 3,6,8-tribromoquinolines via cascade cyclization of N -(3-phenylprop-2-ynyl)anilines employing N -bromosuccinimide as an electrophile. The metal-free process is carried out under mild conditions and is compatible with a variety of substituents. The Sonogashira coupling reaction regioselectively occurs at position C-6 of the obtained products.

Hypervalent iodine compound containing heterocyclic ring as well as preparation method and application thereof

-

, (2019/01/08)

The invention discloses a hypervalent iodine compound containing a heterocyclic ring as well as a preparation method and application thereof. A structure of the compound is shown as a formula (I): theformula (I) is shown in the description, wherein R is selected from hydrogen, halogen, alkyl, alkoxy, halogenated alkyl, halogenated alkoxy, nitryl, cyano, hydroxyl or -COOR'; R' is alkyl or halogenated alkyl; and Het is substituted or non-substituted 1,4-benzopyranone, substituted or non-substituted quinolone, substituted or non-substituted isoquinoline, substituted or non-substituted thiobenzopyranone, substituted or non-substituted coumarin and substituted or non-substituted oxepin. The compound disclosed by the invention is novel in structure and is the hypervalent iodine compound containing the heterocyclic ring; the hypervalent iodine compound is stable in structure and simple in preparation method; and meanwhile, the hypervalent iodine compound has a very good inhibition effect onML-1 and MOLM-13 cells and has an extremely great application prospect on prevention and/or treatment effect on leukemia.
