Check Digit Verification of cas no

The CAS Registry Mumber 1000590-01-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,0,5,9 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1000590-01:
(9*1)+(8*0)+(7*0)+(6*0)+(5*5)+(4*9)+(3*0)+(2*0)+(1*1)=71
71 % 10 = 1
So 1000590-01-1 is a valid CAS Registry Number.

Microwave-assisted, palladium-catalyzed intramolecular direct arylation for the synthesis of novel fused heterocycles

Wu, Jinlong,Nie, Liang,Luo, Jialu,Dai, Weimin

, p. 2728 - 2732 (2008/02/12)

An efficient synthesis of novel fused heterocycles has been established via microwave-assisted palladium-catalyzed intramolecular direct arylation. The acyclic aryl bromides are readily available from microwave-assisted one-pot annulation of N-(2-bromobenzyl)-2-aminophenols and ethyl 2-bromoalkanoates. The intramolecular direct arylation is then performed in the presence of palladium(II) acetate and dppf (10 mol% each) in toluene using potassium carbonate (2 equiv) as the base under microwave heating (150°C, 1 h) to afford the products in 43-99% yields. Steric effect is observed for Ar-Ar bond formation, giving a substantial amount of the debromination byproduct. Georg Thieme Verlag Stuttgart.
