Check Digit Verification of cas no

The CAS Registry Mumber 344257-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,2,5 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 344257-53:
(8*3)+(7*4)+(6*4)+(5*2)+(4*5)+(3*7)+(2*5)+(1*3)=140
140 % 10 = 0
So 344257-53-0 is a valid CAS Registry Number.

A Comparative Study of Pyrolysis and Decarboxylation of β-Substituted t-Butyl Glycidates

Bansal, R.K.,Sethi, K.,Jain, S.K.

, p. 121 - 124 (2007/10/02)

A series of t-butyl glycidates (Ia-i) have been prepared by Darzens condensation of carbonyl compounds with t-butyl chloroacetate in the presence of potassium t-butoxide.The pyrolysis of these esters (I) and the decarboxylation of potassium salts of the corresponding acids result in the same higher aldehydes (II) though in varying proportions.The latter procedure has, however, been found to be superiour in all the cases.Structural assignments of I and II are based on elemental analyses and spectral data (IR, PMR).Resolution of cis- and trans-isomers of I has been achieved in three cases.
