1794-89-4 Usage
General Description
9,10,12,13-Tetrabromostearic Acid is a chemical compound with the molecular formula C18H32Br4O2. It is characterized by the presence of four bromine atoms in its structure. This chemical falls under the category of organic compounds known as fatty acids and conjugates. These are carboxylic acyl compounds and derivatives that contain a chain of an even number of carbon atoms greater than six. Illustratively, this compound is widely used in the manufacturing industry, mainly in the production of flame retardants. Overall, as with any bromide-based substance, it must be handled with care due to potential health hazards associated with bromine.
Check Digit Verification of cas no
The CAS Registry Mumber 1794-89-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,9 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1794-89:
(6*1)+(5*7)+(4*9)+(3*4)+(2*8)+(1*9)=114
114 % 10 = 4
So 1794-89-4 is a valid CAS Registry Number.

RETENTION OF CONFIGURATION IN DOUBLE BOND PROTECTION-DEPROTECTION BY BROMINATION-CATHODIC DEBROMINATION
Husstedt, Urda,Schaefer, Hans J.
, p. 623 - 624 (2007/10/02)
The double bond can be mildly protected by bromination with PyHBr3; deprotection is achieved by cathodic reduction at -1.4 V.The overall yields range from 68 to 99 percent, the configuration of the double bond is retained with at least 96 percent.
