Check Digit Verification of cas no

The CAS Registry Mumber 7399-34-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,9 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7399-34:
(6*7)+(5*3)+(4*9)+(3*9)+(2*3)+(1*4)=130
130 % 10 = 0
So 7399-34-0 is a valid CAS Registry Number.

Continuous Synthesis of Hydantoins: Intensifying the Bucherer-Bergs Reaction

Monteiro, Julia L.,Pieber, Bartholom?us,Corrêa, Arlene G.,Kappe, C. Oliver

, p. 83 - 87 (2016)

A continuous Bucherer-Bergs hydantoin synthesis utilizing intensified conditions is reported. The methodology is characterized by a two-feed flow approach to independently feed the organic substrate and the aqueous reagent solution. The increased interfacial area of the biphasic reaction mixture and the lack of headspace enabled almost quantitative conversions within ca. 30 minutes at 120 °C and 20 bar even for unpolar starting materials. In addition, a selective N(3)-monoalkylation of the resulting heterocycles under batch microwave conditions is reported yielding potential acetylcholinesterase inhibitors.
