The CAS Registry Mumber 68658-38-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,6,5 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 68658-38:
(7*6)+(6*8)+(5*6)+(4*5)+(3*8)+(2*3)+(1*8)=178
178 % 10 = 8

Derivatives of Pentaerythritol, IV. - Identification of By-products in Pentaerythritol Process Liquors

Werle, Peter,Busker, Eberhard,Wolf-Heuss, Elisabeth

, p. 1082 - 1087 (2007/10/02)

Several previously unknown by-products of the pentaerythritol synthesis were identified by comparison of their GC/MS spectra with the spectra of pure compounds.Furthermore, pure 2-hydroxymethyl-2-(methoxymethoxymethyl)-1,3-propandiol (5) was isolated from mother liquors, and the reference compounds 5-hydroxymethyl-1,3-dioxane-5-carboxylic acid (6) and 3--2,2-bis(hydroxymethyl)propanoic acid (7) were synthesized.
