Check Digit Verification of cas no

The CAS Registry Mumber 210241-75-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,2,4 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 210241-75:
(8*2)+(7*1)+(6*0)+(5*2)+(4*4)+(3*1)+(2*7)+(1*5)=71
71 % 10 = 1
So 210241-75-1 is a valid CAS Registry Number.

Microwave enhanced solution synthesis of 1,4-benzodiazepin-5-ones

Santagada, Vincenzo,Perissutti, Elisa,Fiorino, Ferdinando,Vivenzio, Beniamino,Caliendo, Giuseppe

, p. 2397 - 2400 (2007/10/03)

Some 2-methyl-1,4-benzodiazepin-5-ones have been synthesized by the application of microwave irradiation. Conventional heating and microwave irradiation of the reactions were compared. Synthesis by microwave irradiation gave the desired compounds in better yields than those obtained by conventional heating. The overall times for the syntheses were considerably reduced.
