16807-34-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16807-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,0 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 16807-34:
(7*1)+(6*6)+(5*8)+(4*0)+(3*7)+(2*3)+(1*4)=114
114 % 10 = 4
So 16807-34-4 is a valid CAS Registry Number.

Preparation method and application of novel photosensitizer

-

Paragraph 0022; 0032; 0034, (2020/02/14)

The invention relates to a preparation method and application of a novel photosensitizer. The photosensitizer is synthesized for the first time. A general formula compound represented by an intermediate formula (I) is used as a mother core, and is subjected to a Knoevenagel reaction with 4-hydroxybenzaldehyde, 3,5-dibromo-4-hydroxybenzaldehyde and 3,5-diiodo-4-hydroxybenzaldehyde to obtain the general formula photosensitizer represented by a formula (II). The method creatively reserves functional groups (R1, R2) on the intermediate formula (I) and the photosensitizer formula (II), and synthesizes the intermediate and the photosensitizer with S and Se as central atoms (Q) for the first time. The novel photosensitizer provided by the invention solves the technical problems that an existing photosensitizer has a narrow absorption range, a poor therapeutic effect in the visible light range, excessive power of a used light source, and inability to introduce functional groups.
