5243-91-4 Usage
Explanation
This is the given name of the complex organic compound, which may not be widely recognized or used in scientific literature due to it being a non-preferred name.
Explanation
The compound contains a nitrophenyl group, which is a phenyl ring (a six-membered carbon ring with alternating single and double bonds) attached to a nitro group (-NO2).
Explanation
The compound has a pentacyclic structure, meaning it consists of five interconnected rings within a 17-membered azapentacyclo[6.6.5.0~2,7~.0~9,14~0~15,19~]nonadeca core.
Explanation
The compound contains a 16,18-dione functional group, which consists of two carbonyl groups (C=O) located at the 16th and 18th positions of the molecule. This functional group can influence the compound's reactivity and polarity.
Explanation
Due to its complex structure and various functional groups, the compound is likely to exhibit unique chemical properties that may be of interest for further research and investigation.

Check Digit Verification of cas no
The CAS Registry Mumber 5243-91-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,4 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5243-91:
(6*5)+(5*2)+(4*4)+(3*3)+(2*9)+(1*1)=84
84 % 10 = 4
So 5243-91-4 is a valid CAS Registry Number.

Reaction of (1,ω)-N-Acylamino Alcohols with Lawesson's Reagent: Synthesis of Sulfur-Containing Heterocycles
Nishio, Takehiko
, p. 1106 - 1111 (2007/10/03)
Lawesson's reagent [LR: 2,4-bis(p-methoxyphenyl)-1,3,2,4-dithiaphosphetane 2,4-disulfide] is shown to be a valuable reagent for the ready access of sulfur-containing heterocycles: thiazolines 2 starting from the (1,2)-N-acylamino alcohols 1 and benzothiazines 14 from [2-(N-acylamino)phenyl]alkanols 12. Treatment of (1,2)-N-acylamino secondary alcohols 1a-p with LR gave the thiazolines 2a-p via direct conversion of the alcohols to the respective thiols, and the subsequent thionation of the amide carbonyl, followed by cyclization with the elimination of hydrogen sulfide. However, reaction of (1,2)-N-acylamino tertiary alcohols 1q-u with LR yielded the dehydration products 5-7 and 9. Treatment of [2-(N-acylamino)phenyl]alkanols 12a-f with a molar equivalent of LR yielded the 3,1-benzothiazines 14a-f. In this reaction, the [2-(N-acylamino)phenyl]alkanethiols 13a-e were isolated when the corresponding alcohols 12a-e were treated with 0.5 equiv of LR. Further thionation of 13c with LR also gave 3,1-benzothiazine 14c.
