Check Digit Verification of cas no

The CAS Registry Mumber 129156-30-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,5 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129156-30:
(8*1)+(7*2)+(6*9)+(5*1)+(4*5)+(3*6)+(2*3)+(1*0)=125
125 % 10 = 5
So 129156-30-5 is a valid CAS Registry Number.

New Low-Valent Titanium Reagents for Dicarbonyl Coupling and Their Use in a General Method of Annulation

Clive, Derrick L. J.,Zhang, Chengzhi,Murthy, K. S. Keshava,Hayward, William D.,Daigneault, Sylvain

, p. 6447 - 6458 (2007/10/02)

New low-valent titanium reagents have been prepared by reducing TiCl3 (1 mol) with C8K (2 mol) or by reducing TiCl4 (1 mol) with Na-naphthalene (2.75 mol).Ketones carrying a chain that incorporates a suitably placed oxo function (aldehyde or ketone) undergo intramolecular dicarbonyl coupling to produce a bicyclic compound when treated with an excess (16-17 mol of titanium halide per mol of dicarbonyl compound) of one of these reagents.The procedure works well even for highly oxygenated substrates and constitutes a general method of annulation.Other reducing agents besides C8K or Na-naphthalene are suitable, and a brief examination of Na(Hg) and Na-K alloy was made.The C8K/TiCl3 system was also used to convert a cis-1,2-diol into the corresponding olefin.
