Check Digit Verification of cas no

The CAS Registry Mumber 151257-57-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,2,5 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 151257-57:
(8*1)+(7*5)+(6*1)+(5*2)+(4*5)+(3*7)+(2*5)+(1*7)=117
117 % 10 = 7
So 151257-57-7 is a valid CAS Registry Number.

Thiadiazolidine 1-oxide systems for phosphine-free palladium-mediated catalysis

Buckley, Benjamin R.,Neary, Stephen P.

, p. 7988 - 7994 (2010)

We herein report several highly active catalyst systems with thiadiazolidine 1-oxides as ligands for palladium in the Mizoroki-Heck reaction. Excellent yields of stilbenes derived from aryl iodides and bromides have been achieved using as little as 0.00002 mol % catalyst. The ligand/palladium system can be stored as a stock solution open to air at room temperature with no observable loss of activity for a period of several months.

A Novel Method for the Synthesis of Symmetrical Vicinal Tertiary and Secondary Diamines

Katritzky, Alan R.,Fan, Wei-Qiang,Fu, Cong

, p. 3209 - 3213 (2007/10/02)

A variety of symmetrical vicinal tertiary and secondary diamines are readily prepared in good to excellent yields by either Grignard reaction or reduction of the glyoxal bisproducts with benzotriazole and secondary or primary amines.
