Check Digit Verification of cas no
The CAS Registry Mumber 105-11-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 105-11:
(5*1)+(4*0)+(3*5)+(2*1)+(1*1)=23
23 % 10 = 3
So 105-11-3 is a valid CAS Registry Number.

Paragraph 0061; 0071-0078; 0088-0095; 0105-0111, (2021/12/07)
The preparation method of p-benzoquinone dioxime generates intermediate p-benzoquinone monooxime and byproduct alcohol under the action of an acid reaction promoter, and the intermediate is directly reacted with hydroxylamine hydrochloride to generate p-benzoquinone dioxime. The discharge of production waste water is reduced, and the requirement of green color production is met. The by-product ethanol obtained by nitrosation reaction can be finally recovered by distillation together with an organic solvent, so that the utilization rate of raw materials is improved. The whole synthesis process adopts an inert gas to isolate air, avoids the disproportionation and decomposition and intermediate of ethyl nitrite, reduces the generation of side reactions, improves the conversion rate of the reaction, and further improves the yield and purity of the benzoquinone dioxime, the yield is 85.0% - 95.0%, the purity ≥ 99.0 wt % and the melting point are 250 °C - 255 °C.
Hydrohalogenation of 1,4-Benzoquinone Mono- and Bis(O-acyloximes)
Avdeenko,Glinyanaya
, p. 1154 - 1159 (2007/10/03)
Hydrohalogenation of 1,4-benzoquinone O-acyloximes involves intermediate formation of corresponding 1,4-benzoquinone monooximes and hydroxyamino derivatives. The final hydrochlorination products are 2,6-dichloro-4-alkoxyanilines, hydrobromination yields 3,5-dibromo-4-aminophenol as the final product. O-Acyl- and O,O′-diacyl-1,4-benzoquinone dioximes do not undergo hydrohalogenation.
