Check Digit Verification of cas no

The CAS Registry Mumber 126-54-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 126-54:
(5*1)+(4*2)+(3*6)+(2*5)+(1*4)=45
45 % 10 = 5
So 126-54-5 is a valid CAS Registry Number.

Oxymethylation of trifluoromethanesulfonamide with paraformaldehyde in ethyl acetate

Meshcheryakov,Moskalik,Kelling,Schilde,Ushakov,Shainyan

, p. 311 - 316 (2008)

Acid-catalyzed reaction of trifluoromethanesulfonamide with paraformaldehyde in ethyl acetate led to the formation of oxymethylated products that did not form in the reaction carried out in sulfuric acid. Following products were obtained: 5-trifluoromethylsulfonyl-1,3-dioxazinane, 3,7-bis-(trifluoromethylsulfonyl)-1,5,3,7-dioxadiazocane, and a complex of trifluoromethanesulfonamide with 2,4,8,10-tetraoxospiro[5,5]undecene, 1:1. The spiroring resulted from the cyclization of pentaerythritol under the action of formaldehyde. The pentaerythritol formed in its turn by oxymethylation of the methyl group of ethyl acetate with paraformaldehyde followed by the reduction of the COOEt group into CH2 OH by the formaldehyde.

TRANSACETALISATION DE TRIOLS A PARTIR DU DIMETHOXYMETHANE. SELECTIVITE ET APPLICATIONS SYNTHETIQUES

Gras, Jean-Louis,Nouguier, Robert,Mchich, Mohammed

, p. 6601 - 6604 (2007/10/02)

THe LiBr assisted/acid catalyzed transacetalation of triols from DMM affords a highly selective method for the synthesis of hydroxy compounds bearing a dioxane ring.These compounds might further conveniently be alkylated by phase transfer catalyzis.
