Check Digit Verification of cas no

The CAS Registry Mumber 84801-92-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,8,0 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84801-92:
(7*8)+(6*4)+(5*8)+(4*0)+(3*1)+(2*9)+(1*2)=143
143 % 10 = 3
So 84801-92-3 is a valid CAS Registry Number.

Iodine-promoted synthesis of acylindolizine derivatives from acetylenecarboxylates and pyridinium, isoquinolinium, or quinolinium ylides

Liu, Juanjuan,Yan, Peiyun,Li, Yan,Zhou, Zhengquan,Ye, Weijian,Yao, Juan,Wang, Cunde

, p. 617 - 625 (2014/04/03)

An iodine-promoted synthesis of acylindolizinecarboxylates via 1,3-dipolar cycloaddition of nitrogen ylides with acetylenecarboxylates and subsequent aromatization for the generation of a wide range of structurally interesting, pharmacologically and photoelectrically significant compounds is reported. Only readily available materials, mild conditions, and operationally trivial reaction protocols were required. Graphical abstract: [Figure not available: see fulltext.]
