Check Digit Verification of cas no
The CAS Registry Mumber 2855-02-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,5 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2855-02:
(6*2)+(5*8)+(4*5)+(3*5)+(2*0)+(1*2)=89
89 % 10 = 9
So 2855-02-9 is a valid CAS Registry Number.

Paragraph 0016; 0028; 0031; 0034; 0038; 0040; 0044, (2019/04/30)
The invention provides a synthesis method of 3, 5-dichlorobenzene formyl chloride, relating to the technical field of fine chemical engineering. The synthesis method of 3.5-dichlorobenzene formyl chloride comprises the following steps: taking isophthalic acid and trichlorotoluene as raw material under the action of a catalyst reacting at 50-150 DEG C to obtain crude m-phthaloyl chloride; distilling crude m-phthaloyl chloride under reduced pressure at 0.098mpa to obtain refined m-phthaloyl chloride and catalyst; chlorine is introduced at 70-150 DEG C for 4 hours at the rate of 100 mL/min-200 mL/min to obtain 5-dichlorobenzene formyl chloride. The decarbonylation of distilled 5-chloroisophthaloyl chloride is carried out under the action of catalyst at 200-280 DEG C to obtain 3,5-dichlorobenzene formyl chloride. The synthesis method of 3,5-dichlorobenzene formyl chloride has the advantages of high conversion rate, simple operation, little pollution and the like.
