99842-48-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99842-48-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,4 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99842-48:
(7*9)+(6*9)+(5*8)+(4*4)+(3*2)+(2*4)+(1*8)=195
195 % 10 = 5
So 99842-48-5 is a valid CAS Registry Number.

An organophotoredox-catalyzed redox-neutral cascade involving: N -(acyloxy)phthalimides and allenamides: Synthesis of indoles

Das, Sanju,Azim, Aznur,Hota, Sudhir Kumar,Panda, Satya Prakash,Murarka, Sandip,De Sarkar, Suman

supporting information, p. 13130 - 13133 (2021/12/16)

An organophotoredox-catalyzed radical cascade of allenamides and alkyl N-(acyloxy)phthalimides for the synthesis of indoles is documented. The method features mild and robust reaction conditions, and exhibits broad scope. The tandem process enriches the l

Transition-Metal-Free Stereoselective Borylation of Allenamides

García, Lorena,Sendra, Jana,Miralles, Núria,Reyes, Efraim,Carbó, Jorge J.,Vicario, Jose L.,Fernández, Elena

supporting information, p. 14059 - 14063 (2018/09/10)

Complete stereocontrol on the transition-metal-free hydroboration of the distal double bond of allenamides could be achieved when allenamides contained acetyl substituents, which provided exclusively the Z-isomer. The consecutive Pd-catalyzed cross-coupli

Selective cleavage of the N-propargyl group from sulfonamides and amides under ruthenium catalysis

Wang, Jingjing,Li, Feng,Pei, Wenlong,Yang, Mixue,Wu, Yidan,Ma, Danyang,Zhang, Furong,Wang, Jianhui

supporting information, p. 1902 - 1905 (2018/04/19)

The selective cleavage of the N-propargyl group from sulfonamides and amides under ruthenium catalysis is described. The reaction tolerates a broad range of functional groups, and the desired products were obtained in 10–95% yield.
