Check Digit Verification of cas no

The CAS Registry Mumber 295324-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,5,3,2 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 295324-71:
(8*2)+(7*9)+(6*5)+(5*3)+(4*2)+(3*4)+(2*7)+(1*1)=159
159 % 10 = 9
So 295324-71-9 is a valid CAS Registry Number.

Studies on the Wittig reaction (XXX): Stereoselective synthesis and bioactivity of 1-aryl-6-(1,2,4-triazol-1-yl)-1-hexenes

Lu, Shui-Ming,Xiao, Wen-Jing,Huang, Wen-Fang,Wu, Tian-Jie

, p. 195 - 203 (2000)

Twelve 1-aryl-6-(1,2,4-triazol-1-yl)-1-hexenes 4 were synthesized by N-alkylation of alkenyl bromides 3, which were obtained by the Wittig reaction of 5-hydroxypentyltriphenylphosphonium bromide 1 with various aromatic aldehydes and subsequent bromination

One-pot synthesis of benzo[f]quinolin-3-ones and benzo[a]phenanthridein-5- ones by the photoanuulation of 6-chloropyridin-2-ones and 3-chloroisoquinolin-1- ones to phenylacetylene

Wang, Ren,Lu, Shen-Ci,Zhang, Yi-Ming,Shi, Zong-Jun,Zhang, Wei

supporting information; experimental part, p. 5802 - 5808 (2011/10/02)

The one-pot synthesis of benzo[f]quinolin-3-ones and benzo[a] phenanthridein-5-ones was achieved by the inter- and intramolecular photoannulation of 6-chloropyridin-2-ones and 3-chloroisoquinolin-1-ones with phenylacetylene or tethered phenylacetylene. The reactions were proceeded by photoaddition of 6-chloropyridin-2-ones and 3-chloroisoquinolin-1-ones to phenylacetylene to give the chlorine-substituted stilbenoids, and then 6π electrocyclization of the stilbenoids and oxidation aromatization to afford the polycyclic products.
