3491-57-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3491-57-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,9 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3491-57:
(6*3)+(5*4)+(4*9)+(3*1)+(2*5)+(1*7)=94
94 % 10 = 4
So 3491-57-4 is a valid CAS Registry Number.

Method for Carrying Out Multiphase Aldol Condensation Reactions to Give Mixed a, beta-Unsaturated Aldehydes

-

Paragraph 0058-0060; 0062, (2014/02/15)

The invention relates to a continuous method for carrying out a multiphase aldol condensation reaction to obtain mixed α, β-unsaturated aldehydes by reacting a mixture of two aliphatic aldehydes having different numbers of carbon atoms, i.e. 2 to 5, in the molecule in a vertical tubular reactor in a concurrent flow in the presence of an aqueous solution of a basically reacting compound. In said method, the aldehyde mixture is dispersed in the aqueous phase in the form of drops, and the aqueous solution of the basically reacting compound flows through the tubular reactor as a continuous phase in laminar conditions.
