Check Digit Verification of cas no

The CAS Registry Mumber 158009-86-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,0,0 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 158009-86:
(8*1)+(7*5)+(6*8)+(5*0)+(4*0)+(3*9)+(2*8)+(1*6)=140
140 % 10 = 0
So 158009-86-0 is a valid CAS Registry Number.

Stereoselective synthesis of activated 2-arylazetidines via imino-aldol reaction

Ghorai, Manas K.,Das, Subhomoy,Das, Kalpataru,Kumar, Amit

, p. 9042 - 9049 (2015/09/01)

A simple and efficient synthetic route to substituted N-sulfinyl and N-sulfonyl azetidines is described involving imino-aldol reaction of ester enolates with racemic and non-racemic aldimines for obtaining β-amino esters as a key step. These β-amino ester

δ-Amino β-keto Esters, a designed polyfunctionalized chiral building block for alkaloid synthesis. Asymmetric synthesis of (R)-(+)-2-phenylpiperidine and (-)-SS20846A

Davis, Franklin A.,Chao, Bin,Fang, Tianan,Szewczyk, Joanna M.

, p. 1041 - 1043 (2007/10/03)

δ-Amino β-keto esters 3 and 11 are designed polyfunctionalized chiral building blocks for alkaloid synthesis and are prepared in one step from the corresponding sulfinimine (N-sulfinyl imine). Concise highly enantioselective four-step syntheses of 2-phenylpiperidine (7) and SS20846A (14) from 3 and 11, respectively, are described.

Asymmetric Synthesis of (R)-(+)-β-Phenylalanine from (S)-(+)-Benzylidene-p-toluenesulfinamide. Regeneration of the Sulfinimine Precursor

Davis, Franklin A.,Reddy, Rajarathnam E.,Szewczyk, Joanna M.
