Check Digit Verification of cas no

The CAS Registry Mumber 99430-44-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,3 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 99430-44:
(7*9)+(6*9)+(5*4)+(4*3)+(3*0)+(2*4)+(1*4)=161
161 % 10 = 1
So 99430-44-1 is a valid CAS Registry Number.

Synthesis and structure of 2-aryl-5,5-disubstituted-1,3-dioxanes and conversion into chiral (1,1,1-trishydroxymethyl) methane derivatives

Gardiner, John M,Mather, Paul,Morjan, Ramy,Pritchard, Robin G,Warren, John E,Cooper, Malcolm L,Ferwanah, Abd El-Rahman S,Abu-Tiem, Omar S

, p. 2091 - 2094 (2007/10/03)

Pentaerythritol, (1,1,1-trishydroxymethyl)methyl methane and (1,1,1-trishydroxymethyl)nitromethane are converted into 2-aryl-5,5-bis(hydroxymethyl), 2-aryl-5-hydroxymethyl-5-methyl- or 2-aryl-5-hydroxymethyl-5-nitro-1,3-dioxanes and a range of derivatives. X-Ray and NMR analysis establishes that the latter is obtained as a single diastereomer whose structure is unambiguously determined. These materials can be elaborated to chiral derivatives of the starting (1,1,1-trishydroxymethyl) methanes.

CONFORMATION OF 5,5-DISUBSTITUTED 2,2-DIMETHYL-1,3-DIOXANES

Kraiz, B. O.

, p. 387 - 392 (2007/10/02)

It was established by PMR spectral data that in solutions of derivatives of 5-acetoxymethyl-, 5-methyl-, and 5-hydroxymethyl-2,2-dimethyl-1,3-dioxanes with nitrogen-containing substituents (2,4-disubstituted 1,3,5-triazin-6-ylamino, benzamido, and nitro g
