88491-17-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 88491-17-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,4,9 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 88491-17:
(7*8)+(6*8)+(5*4)+(4*9)+(3*1)+(2*1)+(1*7)=172
172 % 10 = 2
So 88491-17-2 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)

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.
