4973-73-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4973-73-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,7 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4973-73:
(6*4)+(5*9)+(4*7)+(3*3)+(2*7)+(1*3)=123
123 % 10 = 3
So 4973-73-3 is a valid CAS Registry Number.

Room Temperature One-Step Conversion from Elemental Sulfur to Functional Polythioureas through Catalyst-Free Multicomponent Polymerizations

Tian, Tian,Hu, Rongrong,Tang, Ben Zhong

, p. 6156 - 6163 (2018)

The utilization of sulfur is a global concern, considering the abundant and cheap source of sulfur from nature and petroleum industry, its limited consumption, and the safety/environmental problems caused during storage. The economic and efficient transformation of sulfur remains to be a great challenge for both academia and industry. Herein, a room temperature conversion from sulfur to functional polythioureas was reported through a catalyst-free multicomponent polymerization of sulfur, aliphatic diamines, and diisocyanides in air with 100% atom economy. The polymerization enjoys quick reaction and wide monomer scope, which affords 16 polythioureas with well-defined structures, high molecular weights (Mws up to 242 500 g/mol), and excellent yields (up to 95%). The polythioureas can be utilized to detect mercury pollution with high sensitivity (Ksv = 224 900 L/mol) and high selectivity, clean Hg2+ with high removal efficiency (>99.99%) to achieve drinking water standard, and monitor the real-time removal process by fluorescence.

Supramolecular compounds from multiple ugi multicomponent macrocyclizations: Peptoid-based cryptands, cages, and cryptophanes

Rivera, Daniel G.,Wessjohann, Ludger A.

, p. 7122 - 7123 (2007/10/03)

The first 3-fold multicomponent macrocyclizations of trifunctional building blocks were developed to produce, in one pot, cryptands, cages, and cryptophanes with peptoid tethers carrying additional recognition motifs. The straightforward, efficient, and d
