Check Digit Verification of cas no

The CAS Registry Mumber 1608129-88-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,8,1,2 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1608129-88:
(9*1)+(8*6)+(7*0)+(6*8)+(5*1)+(4*2)+(3*9)+(2*8)+(1*8)=169
169 % 10 = 9
So 1608129-88-9 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.
