1309952-39-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1309952-39-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,9,5 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1309952-39:
(9*1)+(8*3)+(7*0)+(6*9)+(5*9)+(4*5)+(3*2)+(2*3)+(1*9)=173
173 % 10 = 3
So 1309952-39-3 is a valid CAS Registry Number.

Modular access to N-substituted cis-3,5-diaminopiperidines

Blond, Aurelie,Dockerty, Paul,Alvarez, Raquel,Turcaud, Serge,Lecourt, Thomas,Micouin, Laurent

, p. 12236 - 12242 (2014/01/06)

A sequence of oxidative cleavage/reductive amination/hydrogenolysis enables the preparation of N-substituted cis-3,5-diaminopiperidines from a readily available bicyclic hydrazine. This new synthetic route provides a simple and general access to RNA-friendly fragments with a good chemical diversity.

Stereoselective synthesis of fluorinated 1,3- cis -diaminocyclopentanes

Pasco, Morgane,Moumne, Roba,Lecourt, Thomas,Micouin, Laurent

experimental part, p. 5137 - 5142 (2011/08/06)

Several fluorinated 1,3-diaminocyclopentanes, previously reported to be useful RNA structural probes, can be prepared in a diastereoselective manner from a single bicyclic hydrazine precursor, in 3 to 9 steps.
