Check Digit Verification of cas no
The CAS Registry Mumber 619-33-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 619-33:
(5*6)+(4*1)+(3*9)+(2*3)+(1*3)=70
70 % 10 = 0
So 619-33-0 is a valid CAS Registry Number.

Reactions of α-monochloro- and α,α-dichloro-β-oxoaldehyde acetals with bases
Guseinov
, p. 663 - 665 (2007/10/03)
α,α-Dichloro-β-oxoaldehyde diethyl acetals decompose under the action of bases (NaOH, MeONa) with cleavage of the carbon-carbon bond and formation of carboxylic acids or their esters and the dichloroacetaldehyde diethyl acetal carbanion. The latter reacts in situ with benzaldehyde to form stable α-chloro-α,β-epoxyacetal. α-Chloro-α-formyl-γ-butyrolactone diethyl acetal is transformed into α-chloro-α-diethoxymethyl-γ-hydroxybutyric acid under the action of an alkali.
