29683-23-6 Usage
General Description
Tetrahydrothiopyran-4-ol is a sulfur containing heterocyclic building block. Tetrahydrothiopyran-4-ol can be synthesized from tetrahydrothiopyran-4-one. It participates in the synthesis of 4-hydroxyl-1-methyltetrahydrothiopyranium iodide.
Check Digit Verification of cas no
The CAS Registry Mumber 29683-23-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,6,8 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 29683-23:
(7*2)+(6*9)+(5*6)+(4*8)+(3*3)+(2*2)+(1*3)=146
146 % 10 = 6
So 29683-23-6 is a valid CAS Registry Number.

Stereoselective direct reductive amination of ketones with electron-deficient amines using Re2O7/NaPF6 catalyst
Das, Braja Gopal,Ghorai, Prasanta
supporting information, p. 4379 - 4382 (2013/08/23)
The first example of direct reductive amination (DRA) of ketones with electron-deficient amines (EDA) such as Cbz-, Boc-, EtOCO-, Fmoc-, Bz-, ArSO2-, etc. protected amines have been achieved using catalytic Re2O7/NaPF6. Excellent chemoselectivities as well as diastereoselectivity (for 2-alkyl cyclohexanones) were obtained. The Royal Society of Chemistry 2013.
