Check Digit Verification of cas no

The CAS Registry Mumber 129527-18-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,5,2 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 129527-18:
(8*1)+(7*2)+(6*9)+(5*5)+(4*2)+(3*7)+(2*1)+(1*8)=140
140 % 10 = 0
So 129527-18-0 is a valid CAS Registry Number.

Oxidative cyclization of 3-cinnamoyltropolones with I2/DMSO/ H2SO4 system

Gao, Wentao,Li, Yang,Zhang, Hong,Chang, Mingqin,Imafukub, Kimiaki

experimental part, p. 1107 - 1112 (2010/03/01)

(Chemical Equation Presented) In this study, a facile and general method synthesizing flavone-like 2-aryl-4,9-dihydrocyclohepta[b]-pyran-4,9-diones (2a-y) from 3-cinnamoyltropolones (1a-y) via oxidative cyclization reaction by using I2/DMSO/Hs

, p. 891 - 892 (2007/10/02)

3-Acetyltropolone (1) reacted with 2-methoxybenzaldehyde (2a) in the presence of ethyl orthoformate and perchloric acid to afford 2-(2-methoxyphenyl)-4,9-dihydrocycloheptapyran-4,9-dione (3a).The reactions with 3,4-dimethoxybenzaldehyde (2b), vanillin (2c), and piperonal (2d) gave respectively the corresponding products 3b-d.The reaction with benzaldehyde (2e) gave uncyclized 3-cinnamoyltropolone (4).
