Check Digit Verification of cas no

The CAS Registry Mumber 74280-23-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,8 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74280-23:
(7*7)+(6*4)+(5*2)+(4*8)+(3*0)+(2*2)+(1*3)=122
122 % 10 = 2
So 74280-23-2 is a valid CAS Registry Number.

N-Substituted (Sarcosylamino)benzophenones. Their Synthesis and Conversion into Heterocycles

Hirai, Kentaro,Ishiba, Teruyuki,Sugimoto, Hirohiko,Fujishita, Toshio

, p. 4489 - 4493 (2007/10/02)

A synthetic study of N-substituted (sarcosylamino)benzophenones 2 is described.The target molecules 2 were found to be reactive under neutral conditions, affording intramolecularly cyclized products.Compounds 6a and 13a were converted into pyrazinoquinazoline 9a and pyrazinoquinoline 18a, respectively.The new heterocycles were characterized, and possible mechanisms are proposed for their formation.
