Check Digit Verification of cas no

The CAS Registry Mumber 52458-08-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,4,5 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 52458-08:
(7*5)+(6*2)+(5*4)+(4*5)+(3*8)+(2*0)+(1*8)=119
119 % 10 = 9
So 52458-08-9 is a valid CAS Registry Number.

Ligands for Palladium-Catalyzed Cross-Couplings of Alkyl Halides: Use of an Alkyldiaminophosphane Expands the Scope of the Stille Reaction

Tang, Haifeng,Menzel, Karsten,Fu, Gregory C.

, p. 5079 - 5082 (2003)

Alkyldiaminophosphanes (PR(NR′2)2) are a new class of ligands for palladium-catalyzed cross-couplings of alkyl halides (see scheme). In comparison with trialkylphosphanes, alkyldiaminophosphanes furnish more versatile catalysts for Stille reactions of alkyl bromides and achieve efficient couplings with both vinyl and aryl stannanes, Furthermore, Pd/PR(NR′2)2 provides the first method for accomplishing Stille cross-couplings of simple alkyl iodides that bear β-hydrogen atoms.
