16177-47-2 Usage
General Description
1,2,3,4,5-Pentachloro-5-Methylcyclopentadiene is a highly toxic and potentially carcinogenic chemical compound. It is a chlorinated derivative of cyclopentadiene, which is commonly used in the production of pesticides and other industrial chemicals. Due to its high toxicity, it is considered a hazardous material and should be handled with extreme caution. Exposure to 1,2,3,4,5-Pentachloro-5-Methylcyclopentadiene can cause severe health effects, including respiratory irritation, skin burns, and damage to the central nervous system. As such, it is important to follow proper safety protocols when working with or around this chemical, and to seek medical attention immediately if exposed.
Check Digit Verification of cas no
The CAS Registry Mumber 16177-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,1,7 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 16177-47:
(7*1)+(6*6)+(5*1)+(4*7)+(3*7)+(2*4)+(1*7)=112
112 % 10 = 2
So 16177-47-2 is a valid CAS Registry Number.

Facial Selectivity in the Diels-Alder Reactions of 5-Chloro-, 5-Bromo-, and 5-Iodo-l,3-cyclopentadiene and Derivatives
Wellman, Mark A.,Burry, Lori C.,Letourneau, Johnathon E.,Bridson, John N.,Miller, David O.,Jean Burnell
, p. 939 - 946 (2007/10/03)
A variety of dienophiles was used to assess the facial selectivity of Diels-Alder reactions in a series of 1,3-cyclopentadiene derivatives (1-3, 6-10) in which chlorine, bromine, and iodine were planenonsymmetric atoms pitted against hydrogen or methyl at C-5. The results were rationalized in terms of the major factor controlling the facial selectivity being related to steric hindrance between the diene and the dienophile. Selectivity did not correlate with reactivity. Facial selectivity in the reactions with 4-phenyl-l,2,4-triazoline-3,5-dione as the dienophile was also influenced by a second significant factor, postulated to be filled-orbital repulsion with the halogen substituent.
