Check Digit Verification of cas no

The CAS Registry Mumber 1132641-31-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,2,6,4 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1132641-31:
(9*1)+(8*1)+(7*3)+(6*2)+(5*6)+(4*4)+(3*1)+(2*3)+(1*1)=106
106 % 10 = 6
So 1132641-31-6 is a valid CAS Registry Number.

Umpolung of o-Hydroxyaryl Azomethine Ylides: Entry to Functionalized ?-Aminobutyric Acid under Phosphine Catalysis

Chen, Qingqing,Bao, Yishu,Yang, Xiuqin,Dai, Zonghao,Yang, Fulai,Zhou, Qingfa

, p. 5380 - 5383 (2018)

A phosphine-catalyzed reaction between o-hydroxyaryl azomethine ylides and MBH carbonates provides access to highly functionalized ?-aminobutyric acid derivatives in moderate to good yields. Mechanistically, the reaction involves a phosphine-catalyzed tandem SN2′/2-aza-Cope rearrangement/intramolecular addition process.

Ligand-Dependent Regiodivergent Enantioselective Allylic Alkylations of α-Trifluoromethylated Ketones

Zhu, Yi,Ni, Yifan,Lu, Chenxi,Wang, Xiaochen,Wang, Yi,Xue, Xiao-Song,Pan, Yi

, p. 2443 - 2448 (2021/04/05)

The asymmetric introduction of the CF3 unit is a powerful tool for modifying pharmacokinetic properties and slowing metabolic degradation in medicinal chemistry. A catalytic and enantioselective addition of α-CF3 enolates allows for expeditious access to

Synthesis of β-Lactams via Enantioselective Allylation of Anilines with Morita-Baylis-Hillman Carbonates

Krieck, Sven,Lange, Markus,Schüler, Philipp,Vilotijevic, Ivan,Westerhausen, Matthias,Zi, You

, p. 575 - 580 (2020/03/27)

Enantioenriched β-lactams are accessed via enantioselective allylation of anilines with Morita-Baylis-Hillman carbonates followed by a base-promoted cyclization. The resulting 3-methyleneazetidin-2-ones are amenable to diastereoselective functionalization
