1021273-74-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1021273-74-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,2,7 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1021273-74:
(9*1)+(8*0)+(7*2)+(6*1)+(5*2)+(4*7)+(3*3)+(2*7)+(1*4)=94
94 % 10 = 4
So 1021273-74-4 is a valid CAS Registry Number.

METHOD FOR PRODUCING 2-HYDRAZINOBENZOTHIAZOLE DERIVATIVE

-

Paragraph 0130; 0132, (2020/06/15)

The present invention provides a novel method for producing a 2-hydrazinobenzothiazole derivative. The present invention also provides a method for producing a compound by using the 2-hydrazinobenzothiazole derivative obtained by the production method, and a composition that contains the compound. The present invention also provides a polymerizable composition that is useful in producing film-shaped polymers and contains the compound obtained by the production method. The invention of the present application provides a method for producing a compound represented by general formula (I-C), the method including a step of reacting a compound represented by general formula (I-B) with a compound represented by general formula (I-A) in the presence of at least one compound selected from the group consisting of metal amides, metal hydrides, metal alkoxides, and organic alkali metals. A compound derived from the compound produced by the production method, and a composition that contains the compound are also provided.

Method for producing ester group-containing compound being useful for optical material applications such as optical compensation films

-

Paragraph 0192; 0194, (2019/07/16)

The present invention provides a novel method for producing an ester group-containing compound and a derivative produced by using the compound as a synthetic intermediate. The present invention also provides a polymerizable composition containing the compound obtained by the production method and a film-shaped polymer obtained by polymerizing the polymerizable composition. The present invention is a method for producing an ester group-containing compound, the method including a mixing step of mixing a condensing agent, a Bronsted acid, carboxylic acid, and phenol or alcohol to prepare a reaction mixture. The Bronsted acid is selected from anything other than the condensing agent, the carboxylic acid, and the phenol.
