7203-96-5 Usage
General Description
2-Thioxohexamethyleneimine is a chemical compound with the molecular formula C7H12N2S. It is also known as thiourea hexamethyleniminium salt and is used in the production of rubber and plastic products. It is a white crystalline solid that is soluble in water and has a melting point of 172-177°C. It is a key ingredient in the synthesis of sulfur-containing organic compounds and is also used as a catalyst in organic reactions. Additionally, 2-Thioxohexamethyleneimine has applications in the pharmaceutical industry for the synthesis of certain drugs and in the production of agricultural chemicals. It should be handled and stored with caution, as it may cause skin and eye irritation and should be kept away from heat and open flames.
Check Digit Verification of cas no
The CAS Registry Mumber 7203-96-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,0 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7203-96:
(6*7)+(5*2)+(4*0)+(3*3)+(2*9)+(1*6)=85
85 % 10 = 5
So 7203-96-5 is a valid CAS Registry Number.

Amide (A)–thioamide (T) interconversions using Ph3SiSH (A to T) and Ph3SnOH (T to A) reagents
Arias-Ugarte, Renzo N,Sharma, Hemant K,Pannell, Keith H
, p. 510 - 513 (2016/07/16)
Ph3SiSH transforms amides to thioamides and Ph3SnOH performs the reverse process, with the concomitant formation of Ph3SiOH (or Ph3SiOSiPh3) and Ph3SnSSnPh3, respectively. The chemistry is a delightful illustration of the oxophilicity of silicon compared to the thiophilicity of tin and occurs under relatively mild conditions, and for amide to thioamide transformation requires no amide activation. The chemistry is in accord with available data for Si?(S)(O), Sn?(O)(S) and C?(O)(S) bond energies. Copyright
