55956-38-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55956-38-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,9,5 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55956-38:
(7*5)+(6*5)+(5*9)+(4*5)+(3*6)+(2*3)+(1*8)=162
162 % 10 = 2
So 55956-38-2 is a valid CAS Registry Number.

A Convenient Method for the Preparation of Bicyclic Dihydro-1,4-dioxins, Dihydro-1,4-oxathiins, Dihydro-1,4-dithiins and Related Compounds

Fjeldskaar, Inger Reidun,Rongved, Paul,Skatteboel, Lars

, p. 477 - 486 (2007/10/02)

Acid catalysed reactions of cyclic α-hydroxy ketones with ethylene glycol, 2-mercaptoethanol and 1,2-ethanedithiol furnished in most cases the corresponding dihydro-1,4-dioxin, dihydro-1,4-oxathiin and dihydro-1,4-dithiin derivatives, respectively, in high yields.Similar reactions of 2-hydroxycyclooctanone and 2-hydroxycyclododecanone with 1,3-propanediol gave the corresponding bicyclic dihydro-1,4-dioxepins as sole products.From 2-hydroxycyclohexanone and 1,3-propanedithiol the corresponding bicyclic dihydro-1,4-dithiepin was obtained.In some cases the reaction gave rise to mixtures of isomeric products.A general mechanism for the reaction is proposed.
