Check Digit Verification of cas no

The CAS Registry Mumber 1589518-79-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,9,5,1 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1589518-79:
(9*1)+(8*5)+(7*8)+(6*9)+(5*5)+(4*1)+(3*8)+(2*7)+(1*9)=235
235 % 10 = 5
So 1589518-79-5 is a valid CAS Registry Number.

Facile synthesis of indene and fluorene derivatives through AlCl3-catalyzed cyclization of in situ formed iminium ions

Chen, Lei,Teng, Wei,Geng, Xin-Le,Zhu, Yi-Fan,Guan, Yong-Hong,Fan, Xiaohui

, (2017/10/05)

A simple AlCl3-catalyzed condensation/cyclization cascade process between aldehydes and sulfonamide is reported, in which two new bonds and one five-membered ring are simultaneously formed with water as the byproduct. This method provides a rapid access to indenamine and 9-aminofluorene derivatives. Additionally, these products can be transformed into corresponding indanones and fluorenones under the developed conditions.
