Check Digit Verification of cas no
The CAS Registry Mumber 20871-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,7 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20871-40:
(7*2)+(6*0)+(5*8)+(4*7)+(3*1)+(2*4)+(1*0)=93
93 % 10 = 3
So 20871-40-3 is a valid CAS Registry Number.

An amide unit was constructed from aryl halide and titanium-isocyanate complex prepared from TiCl4 under atmospheric pressure of molecular nitrogen and carbon monoxide in the presence of a palladium catalyst.With this combination system of carbonylation and nitrogenation, isoindolinone and quinazolinone derivatives were synthesized from o-halophenyl alkyl ketone in one step.The reaction proceeds through the oxidative addition of enol lactone, generated by palladium-catalyzed carbonylation to o-halophenyl alkyl ketone, to titanium-isocyanate complex.
