1473-33-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1473-33-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,7 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1473-33:
(6*1)+(5*4)+(4*7)+(3*3)+(2*3)+(1*3)=72
72 % 10 = 2
So 1473-33-2 is a valid CAS Registry Number.

Synthesis of thioureas in ionic liquid medium

Halimehjani, Azim Ziyaei,Farahbakhsh, Fataneh

, p. 284 - 288 (2013/08/26)

A highly efficient procedure for the synthesis of symmetrical thioureas by means of simple condensation of primary amines and carbon disulfide in 1-butyl-3-methylimidazolium chloride [BMIM][Cl] as a cheap and commercially available ionic liquid is presented. This procedure works for aromatic and aliphatic primary amines and give high to excellent yields of symmetrical thioureas without need for any catalyst or tedious work-up.
