46872-42-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 46872-42-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,6,8,7 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 46872-42:
(7*4)+(6*6)+(5*8)+(4*7)+(3*2)+(2*4)+(1*2)=148
148 % 10 = 8
So 46872-42-8 is a valid CAS Registry Number.

Titanium isopropoxide promoted tandem self-cross and ring-closing metathesis approach for the synthesis of macrotetralides

Muthusamy, Sengodagounder,Azhagan, Datshanamoorthy

, p. 363 - 370 (2014/01/23)

A new approach is demonstrated for the synthesis of macrotetralides through an olefin metathesis reaction using Grubbs' second-generation catalyst with titanium isopropoxide as a cocatalyst. This study demonstrates a tandem self-cross and ring-closing metathesis approach to form macrocyclic ring systems with excellent (E) selectivity. The reaction was optimized with regard to functional group, catalyst, solvent, Lewis acid, concentration, and temperature. A new approach is demonstrated for the synthesis of macrotetralides through tandem self-cross and ring-closing metathesis reactions using Grubbs' second-generation catalyst and titanium isopropoxide.
