Check Digit Verification of cas no

The CAS Registry Mumber 1185290-99-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,5,2,9 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1185290-99:
(9*1)+(8*1)+(7*8)+(6*5)+(5*2)+(4*9)+(3*0)+(2*9)+(1*9)=176
176 % 10 = 6
So 1185290-99-6 is a valid CAS Registry Number.

New synthesis of aryl and heteroaryl N-acylureas via microwave-assisted palladium-catalysed carbonylation

Liptrot, David,Alcaraz, Lilian,Roberts, Bryan

supporting information; experimental part, p. 2183 - 2188 (2010/11/04)

A new, practical synthesis of aryl and heteroaryl N-acylureas has been developed via palladium-catalysed carbonylation of aryl or heteroaryl halides in the presence of urea nucleophiles. A range of reactions illustrating the wide scope of this reaction was carried out under microwave irradiation, using either carbon monoxide gas in a vessel equipped with a gas inlet adapter, or molybdenum hexacarbonyl as the carbon monoxide source in standard microwave vials. The reactions proceeded in good to excellent yields. To illustrate the usefulness of this method a one-step synthesis of the important insecticide diflubenzuron is reported.
