Check Digit Verification of cas no

The CAS Registry Mumber 104503-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,5,0 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 104503-23:
(8*1)+(7*0)+(6*4)+(5*5)+(4*0)+(3*3)+(2*2)+(1*3)=73
73 % 10 = 3
So 104503-23-3 is a valid CAS Registry Number.

The cross-coupling reactions of 4-bromoparacyclophane with p-tolylmagnesium bromide in the presence of various palladium and nickel complexes have been studied.It was found that 1,1'-bis(diphenylphosphinoferrocene)palladium dichloride (PdCl2*dppf) s

STERIC HINDERED CYCLOPHANES. PART II. THE SYNTHESIS OF 4-ARYLPARACYCLOPHANES IN THE CROSS-COUPLING OF GRIGNARD REAGENTS

Kus, Piotr,Zemanek, Aleksander

, p. 281 - 284 (2007/10/02)

The cross-coupling of Grignard reagents type Aryl-MgBr with 4-Br-paracyclophane catalyzed by complex of NiCl2 with PPh3 or Ph2PCH2CH2PPh2 was carried out. 4-Aryl-paracyclophanes were prepared in total yields of 10-65percent (Aryl=phenyl, o-tolyl, mesityl, α-naphthyl).The complex of NiCl2 with PPh3 was the most effective catalyst.
