81574-75-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81574-75-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,7 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81574-75:
(7*8)+(6*1)+(5*5)+(4*7)+(3*4)+(2*7)+(1*5)=146
146 % 10 = 6
So 81574-75-6 is a valid CAS Registry Number.

Multiturn Hollow Helices: Synthesis and Folding of Long Aromatic Oligoamides

Ferrand, Yann,Gong, Bing,Huc, Ivan,Kauffmann, Brice,Liu, Rui,Lu, Zhong-Lin,Xu, Wenwu,Zeng, Xiao Cheng,Zhong, Yulong

supporting information, p. 6938 - 6942 (2020/09/15)

Aromatic oligoamides adopting helical conformations are synthesized by coupling carboxyl-terminated basic units having two, four, and eight residues to amine-terminated oligomer precursors. Coupling yields show no noticeable reduction with the size of the

Cerium(IV)-induced nitration of cinnamic acids. Novel remote electrophilic substitution

Peterson, John R.,Do, Hoang D.,Dunham, Andrew J.

, p. 1670 - 1674 (2007/10/02)

The treatment of (E)-3,4-dimethoxycinnamic acid with ceric amonium nitrate in trifluoroacetic acid afforded (E)1,2-dimethoxy-4-nitro-5-(2-nitroethenyl)benzene in 79percent yield.The unusual ipso substitution of the carboxylic acid moiety by a nitro functional center illustrated a new reaction manifold of cerium(IV).Six cinnamic acids were examined to ascertain the generality of the transformation.The bidentate nitrato structure of the metal salt is believed to account for the nitrating ability of this system.
