400745-03-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 400745-03-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,0,7,4 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 400745-03:
(8*4)+(7*0)+(6*0)+(5*7)+(4*4)+(3*5)+(2*0)+(1*3)=101
101 % 10 = 1
So 400745-03-1 is a valid CAS Registry Number.

Palladium-catalyzed direct arylation of heteroaromatic compounds: Improved conditions utilizing controlled microwave heating
Baghbanzadeh, Mostafa,Pilger, Christian,Oliver Kappe
experimental part, p. 8138 - 8142 (2011/11/07)
A versatile and rapid microwave-assisted procedure for the palladium-catalyzed direct arylation of heterocycles by aryl bromides and heteroaryl bromides is described. This novel protocol features short coupling times (10-60 min) and low catalyst loadings
