Check Digit Verification of cas no

The CAS Registry Mumber 19814-75-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,1 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19814-75:
(7*1)+(6*9)+(5*8)+(4*1)+(3*4)+(2*7)+(1*5)=136
136 % 10 = 6
So 19814-75-6 is a valid CAS Registry Number.

Paragraph 0163-0170, (2021/02/02)

The present invention relates to an organic electroluminescent compound represented by chemical formula 1. An organic electroluminescent device comprising the organic electroluminescent compound of the present invention is able to be operated under a lower driving voltage compared to a conventional device with a phosphorescent hast material, and has excellent power efficiency, luminous efficiency, and service life.

Preparation method of 9,9-dimethyl xanthene

-

Paragraph 0016-0019, (2020/10/30)

The invention relates to a safe and efficient preparation method of an important raw material 9,9-dimethyl xanthene of an industrial catalyst Xantphos, and belongs to the technical field of fine chemical engineering. According to the preparation method, diphenyl ether, acetone and an acid catalyst serve as raw materials, a molar ratio of the raw materials is 1:1:(2-5), 9,9-dimethyl xanthene is prepared through a one-pot method, the yield can reach 70%-75%, and the content is 99% or above. According to the method, acid-catalyzed activated acetone and diphenyl ether are adopted for electrophilicsubstitution reaction to replace extremely dangerous trimethylaluminum and xanthone used in the traditional process for reaction, and the method has the characteristics of cheap and easily availableraw materials, safety in operation, high reaction speed, low requirements on production equipment and the like; and the production difficulty of the product is greatly reduced, and the yield of the 9,9-dimethyl xanthene can be rapidly increased.
