Check Digit Verification of cas no

The CAS Registry Mumber 16768-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,7,6 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16768-72:
(7*1)+(6*6)+(5*7)+(4*6)+(3*8)+(2*7)+(1*2)=142
142 % 10 = 2
So 16768-72-2 is a valid CAS Registry Number.

Synthesis method of monomethine cyanine dye

-

Paragraph 0041-0045, (2018/02/04)

The invention relates to a synthesis method of monomethine cyanine dye. The method comprises the following steps: (1) adding N-methyl quinoline-2-thioketone, methyl p-toluenesulfonate, active methyl-containing heterocyclic quaternary ammonium salt and absolute ethyl alcohol into a round-bottom flask; dropwise adding triethylamine; and performing reflux; and (2) performing reduced-pressure distillation on the solution after the reflux in the step (1) to separate out partial solvent, and cooling; and when solid is separated out, performing suction filtration, drying and recrystallizing to finally obtain a finished product of monomethine cyanine dye. The method provided by the invention has the advantages of easiness in operation, high synthesis yield, a few steps and short time, can effectively avoid the purifying treatment of the intermediate product, and realizes high synthesis efficiency and relatively low synthesis cost.
