3818-32-4 Usage
General Description
3-hydroxy-2,2-bis(hydroxymethyl)propionaldehyde, also known as DHA (Dihydroxyacetone), is a simple carbohydrate that is primarily used as an ingredient in sunless tanning products. It is colorless, and it interacts with the amino acids in dead skin cells to produce a brown color change. This chemical is safe for external use and has been approved by the Food and Drug Administration (FDA) for use in cosmetics, including sunless tanning products. However, it could cause certain side effects like skin irritation when applied excessively or if exposed to sensitive areas like the eyes or the mouth.
Check Digit Verification of cas no
The CAS Registry Mumber 3818-32-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,1 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3818-32:
(6*3)+(5*8)+(4*1)+(3*8)+(2*3)+(1*2)=94
94 % 10 = 4
So 3818-32-4 is a valid CAS Registry Number.

ANALYSIS OF THE STRUCTURE OF THE REACTION SYSTEM OF A PROCESS ON THE BASIS OF INTEGRAL CHARACTERISTICS.
Belkin
, p. 341 - 345 (2007/10/02)
In this work the structure of the reactions of the acetaldehyde-formaldehyde condensation process is subjected to systems analysis, based on the dependence of its integral characteristics on the general conditions, and the main routes of detailed experimental verification of the proposed mechanism are suggested.
