13702-02-8 Usage
General Description
Prop-2-yn-1-yl carbamimidothioate, also known as proparacaine, is a local anesthetic that is commonly used in ophthalmic procedures to numb the surface of the eye. It works by blocking the transmission of pain signals from the nerve endings in the eye to the brain, providing temporary relief from discomfort during surgical or diagnostic procedures. Prop-2-yn-1-yl carbamimidothioate is typically administered in the form of eye drops and its effects are usually felt within seconds of application. It is considered safe and effective when used as directed by a healthcare professional, and it is generally well-tolerated with minimal side effects. However, prolonged or excessive use of prop-2-yn-1-yl carbamimidothioate can lead to potential adverse effects, and it should only be used under the supervision of a medical professional.
Check Digit Verification of cas no
The CAS Registry Mumber 13702-02-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,0 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13702-02:
(7*1)+(6*3)+(5*7)+(4*0)+(3*2)+(2*0)+(1*2)=68
68 % 10 = 8
So 13702-02-8 is a valid CAS Registry Number.

Selective oxidations for the preparation of either sulfoxides or sulfones of 2-allyl, 2-propadienyl- and 2-propargylthio-5-chloropyrimidines are described.The 2-propargylsulfone as well as its sulfide is easily isomerized to the isomeric allenes.The unsaturated sulfides are conveniently prepared in a condensation reaction between 1,3-bis-N,N-dimethylamino-2-chlorotrimethinium perchlorate and the respective isothiourea.
