Check Digit Verification of cas no

The CAS Registry Mumber 20174-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,7 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20174-68:
(7*2)+(6*0)+(5*1)+(4*7)+(3*4)+(2*6)+(1*8)=79
79 % 10 = 9
So 20174-68-9 is a valid CAS Registry Number.

The syntheses and crystal structure of novel 5-methyl-3-substituted-1,2,4-triazolo[3,4-b]benzothiazoles

Dong, Heng-Shan,Quan, Bin,Chai, Er-Feng,Mao, Xue-Rong

, p. 41 - 47 (2002)

Novel 5-methyl-3-substituted-1,2,4-triazolo[3,4-b]benzothiazoles were synthesized from o-methylaniline to 5 with various aromatic carbonic acids. The yielded product 6a-e were confirmed by Elemental Analyses, NMR, MS, IR spectra and 6e was investigated with X-ray crystallography. Compound 6e, C24H16N4S, Mr = 392.69, crystallized in the triclinic space group P1? with unit cell parameters a = 9.713(3) ?, b = 14.645(4) ?, c = 15.641(3) ?, α = 113.17(2)°, β=90.11(2)°, γ = 109.29(2)°, V = 1908.1(7) ?3, Z = 4, Dm = 1.366 Mgm-3.

Method for synthesizing 4-methyl-2-benzothiazolehydrazine

-

, (2020/07/12)

The invention discloses a method for synthesizing 4-methyl-2-benzothiazolehydrazine. The method comprises the following steps: carrying out synthesis reaction on o-toluidine and thiocyanate in acid toobtain o-tolylthiourea; carrying out a synthesis reaction on the o-tolylthiourea and a catalyst in water to obtain 2-amino-4-methylbenzothiazole; and carrying out a synthesis reaction on the 2-amino-4-methylbenzothiazole in hydrazine hydrate, so as to obtain the 4-methyl-2-benzothiazolehydrazine. The method for synthesizing the 4-methyl-2-benzothiazolehydrazine, provided by the invention, is simple to operate, less in three wastes, capable of repeatedly applying wastewater, high in product content, good in quality and suitable for industrial mass production.
