Check Digit Verification of cas no

The CAS Registry Mumber 1448363-12-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,3,6 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1448363-12:
(9*1)+(8*4)+(7*4)+(6*8)+(5*3)+(4*6)+(3*3)+(2*1)+(1*2)=169
169 % 10 = 9
So 1448363-12-9 is a valid CAS Registry Number.

Photoinduced and N-bromosuccinimide-mediated cyclization of 2-azido-N-phenylacetamides

Li, Zhan-Shan,Wang, Wei-Xia,Yang, Ji-Dong,Wu, Yue-Wei,Zhang, Wei

, p. 3820 - 3823 (2013/09/02)

An efficient synthesis of quinoxalin-2(1H)-ones or spiro[cyclohexene-1, 2′-imidazol]-4′-ones has been achieved in moderate to high yields by the visible light-induced and N-bromosuccinimide-mediated cyclization reaction of 2-azido-N-phenylacetamides at ambient temperature. Both the regioselectivity and the speed of cyclization are affected by the substituents attached to the phenyl ring. For example, quinoxalin-2-ones are produced as the main products when the substrates bear electron-withdrawing groups at the para-position of the phenyl ring; in contrast, spiro[cyclohexene-1,2′-imidazol]-4′-ones are obtained as the main products when the substrates bear electron-donating groups at the para-position.
