Check Digit Verification of cas no

The CAS Registry Mumber 4467-90-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,6 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4467-90:
(6*4)+(5*4)+(4*6)+(3*7)+(2*9)+(1*0)=107
107 % 10 = 7
So 4467-90-7 is a valid CAS Registry Number.

An efficient method for the synthesis of α-arylated nitroalkanes and α-arylated hydroximoyl chlorides mediated by AlCl3

Tu, Zhijay,Rama Raju,Liou, Tzuo-Rung,Kavala, Veerababurao,Kuo, Chun-Wei,Jang, Yaochung,Shih, Yu-Hsuan,Wang, Chun-Chao,Yao, Ching-Fa

experimental part, p. 2436 - 2442 (2009/07/25)

Friedel-Crafts alkylation of various arenes/heteroarenes to β-nitrostyrenes mediated by aluminum chloride is described. The interesting feature of this methodology pertain the formation of different products by tuning the reaction temperature. α-Arylated

A facile one-pot preparation of isothiocyanates from aldoximes

Kim, Jae Nyoung,Jung, Keum Shin,Lee, Hong Jung,Son, Ji Suk

, p. 1597 - 1598 (2007/10/03)

Isothiocyanates 2a-l were prepared in excellent yields in a one-pot reaction from aldoxime derivatives 1a-l by successive treatment of aldoxime with N-chlorosuccinimide (NCS), thiourea, and triethylamine. The use of HCl/DMF/Oxone system in the reaction instead of NCS was equally effective.
