Check Digit Verification of cas no
The CAS Registry Mumber 71005-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,0 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 71005-33:
(7*7)+(6*1)+(5*0)+(4*0)+(3*5)+(2*3)+(1*3)=79
79 % 10 = 9
So 71005-33-9 is a valid CAS Registry Number.

Synthesizing method for diazonium monomer 4-diazo diphenylamine disulfate
-
Paragraph 0019, (2016/10/10)
The invention discloses a synthesizing method for a diazonium monomer 4-diazo diphenylamine disulfate, and belongs to the technical field of synthesis of photosensitive compounds.The 4-diazo diphenylamine disulfate is prepared by taking an RT base, concentrated sulfuric acid and sodium nitrite as raw materials and dropwise adding concentrated sulfuric acid and sodium nitrite.In the reaction process, ethyl alcohol is not needed to serve as solvent, and 4-diazo diphenylamine salt does not need to be synthesized and then replaced with concentrated sulfuric acid.When 4-diazo diphenylamine disulfate is synthesized through the method, the cost is greatly lowered, the equipment utilization rate is increased, and the yield reaches 80% or above.
