Check Digit Verification of cas no

The CAS Registry Mumber 81541-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,4 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81541-12:
(7*8)+(6*1)+(5*5)+(4*4)+(3*1)+(2*1)+(1*2)=110
110 % 10 = 0
So 81541-12-0 is a valid CAS Registry Number.

Method of preparing powdery diacetal clarifying agent

-

Page/Page column 18, (2019/07/17)

Provided is a method of preparing a powdery diacetal clarifying agent, which comprises mixing an aromatic aldehyde, a polyol, and an acid catalyst in an organic polar solvent, adding a hydrogenating agent and an inorganic silicon-containing agent into the foregoing mixture, and filtering the mixture. The powdery diacetal clarifying agent prepared by the method can have excellent flowability, dispersability, thermal resistance, and color stability. Accordingly, the powdery diacetal clarifying agent does not release stinking odor and incur yellowing at high temperature, allowing the plastic articles to have improved appearance and visual appeal.

Method of preparing diacetal-based clarifying agent

Paragraph 0057-0059, (2015/11/24)

Provided is a method of preparing a diacetal-based clarifying agent, comprising mixing aromatic aldehyde and polyol in the presence of an acid catalyst to undergo a condensation reaction, and adding a safe hydrogenating agent with the mixture. After filtering, drying and grinding steps, a diacetal-based clarifying agent with high purity is obtained by the method. When applying the diacetal-based clarifying agent to the plastic process, the final plastic product not only eliminates the release of stinking odor, but also improves the color stability at high temperature, such that the application of the final plastic product can be improved.
