2816-67-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2816-67-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,1 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2816-67:
(6*2)+(5*8)+(4*1)+(3*6)+(2*6)+(1*7)=93
93 % 10 = 3
So 2816-67-3 is a valid CAS Registry Number.

Synthesizing method of 3,4-heptadione

-

Paragraph 0018; 0027; 0031; 0035, (2017/09/18)

The invention provides a synthesizing method of 3,4-heptadione. The synthesizing method comprises the following steps of (1) using propionaldehyde and butyraldehyde as raw materials, adding a main catalyst, and reacting under the alkaline condition, so as to synthesize 4-hydroxyl-3-heptanone; (2) mixing the 4-hydroxyl-3-heptanone, sulfuric acid and an oxidant to oxidize, so as to obtain the 3,4-heptadione. The synthesizing method of the 3,4-heptadione has the advantages that the main raw materials are the propionaldehyde and butyraldehyde, the obtaining of the raw materials is easy, the cost is low, and the production cost is reduced.
