Check Digit Verification of cas no

The CAS Registry Mumber 134274-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,7 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134274-83:
(8*1)+(7*3)+(6*4)+(5*2)+(4*7)+(3*4)+(2*8)+(1*3)=122
122 % 10 = 2
So 134274-83-2 is a valid CAS Registry Number.

PH-Mediated Selective Synthesis of N-Allylic Alkylation or N-Alkylation Amines with Allylic Alcohols via an Iridium Catalyst in Water

Luo, Nianhua,Zhong, Yuhong,Shui, Hongling,Luo, Renshi

, p. 15509 - 15521 (2021/11/01)

Amination of allylic alcohols is an effective approach in the facile synthesis of N-allylic alkylation or N-alkylation amines. Recently, a series of catalysts were devised to push forward this transformation. However, current synthetic methods are typical

N-Methylcaprolactam as a Dipolar Aprotic Solvent for Iron-Catalyzed Cross-Coupling Reactions: Matching Efficiency with Safer Reaction Media

Bisz, Elwira,Podchorodecka, Pamela,Szostak, Michal

, p. 1196 - 1199 (2019/01/25)

Although iron-catalysis provides a powerful alternative to the more conventional palladium and nickel in the cross-coupling arena, the major limitation is the necessity for carcinogenic N-methylpyrrolidone as a co-solvent in the vast majority of catalytic reactions. Herein, we introduce N-methylcaprolactam as an efficient, non-toxic and practical dipolar aprotic solvent for iron-catalyzed C(sp2)?C(sp3) alkylative cross-coupling of aryl chlorides and tosylates. The utility of this method is reflected by its wide substrate scope, high yields and capacity to cross-couple challenging alkyl organometallics prone to b-hydride elimination and homocoupling. Considering the broad utility of iron-catalyzed cross-coupling, we envision that N-methylcaprolactam will find wide application as a substitute for carcinogenic NMP.
