Check Digit Verification of cas no

The CAS Registry Mumber 1204-28-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,0 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1204-28:
(6*1)+(5*2)+(4*0)+(3*4)+(2*2)+(1*8)=40
40 % 10 = 0
So 1204-28-0 is a valid CAS Registry Number.

N -Hydroxyphthalimide/benzoquinone-catalyzed chlorination of hydrocarbon C-H bond using N -chlorosuccinimide

Li, Zi-Hao,Fiser, Béla,Jiang, Biao-Lin,Li, Jian-Wei,Xu, Bao-Hua,Zhang, Suo-Jiang

supporting information, p. 3403 - 3408 (2019/04/01)

The direct chlorination of C-H bonds has received considerable attention in recent years. In this work, a metal-free protocol for hydrocarbon C-H bond chlorination with commercially available N-chlorosuccinimide (NCS) catalyzed by N-hydroxyphthalimide (NHPI) with 2,3-dicyano-5,6-dichlorobenzoquinone (DDQ) functioning as an external radical initiator is presented. Aliphatic and benzylic substituents and also heteroaromatic ones were found to be well tolerated. Both the experiments and theoretical analysis indicate that the reaction goes through a process wherein NHPI functions as a catalyst rather than as an initiator. On the other hand, the hydrogen abstraction of the C-H bond conducted by a PINO species rather than the highly reactive N-centered radicals rationalizes the high chemoselectivity of the monochlorination obtained by this protocol as the latter is reactive towards the C(sp3)-H bonds of the monochlorides. The present results could hold promise for further development of a nitroxy-radical system for the highly selective functionalization of the aliphatic and benzylic hydrocarbon C-H.

Method for preparing trimellitic anhydride acid chloride through distillation and purification with film evaporator

-

Paragraph 0016; 0017; 0018; 0019; 0020; 0021, (2018/09/08)

The invention specifically relates to a method for preparing trimellitic anhydride acid chloride through distillation and purification with a film evaporator, belonging to the technical field of organic synthesis of fine chemical intermediates. The method comprises the following steps: with trimellitic anhydride and thionyl chloride as raw materials, carrying out a reflux reaction in a solvent under the action of a tri-n-butylphosphine catalyst so as to obtain a reaction solution after the reaction; subjecting the reaction solution to pressure-reduced distillation to remove the solvent and excess thionyl chloride; and then carrying out distillation, separation and purification with the film evaporator, and carrying out cooling to obtain trimellitic anhydride acid chloride. The method provided by the invention has the advantages of simple process, high product purity, recyclability of the solvent and thionyl chloride, and the like, and is suitable for industrial production.
