Check Digit Verification of cas no

The CAS Registry Mumber 1259488-10-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,4,8 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1259488-10:
(9*1)+(8*2)+(7*5)+(6*9)+(5*4)+(4*8)+(3*8)+(2*1)+(1*0)=192
192 % 10 = 2
So 1259488-10-2 is a valid CAS Registry Number.

Chiral Bronsted acid-catalyzed enantioselective friedel-crafts reaction of 4,7-dihydroindoles with trifluoromethyl ketones

Wang, Teng,Zhang, Guang-Wu,Teng, Yuou,Nie, Jing,Zheng, Yan,Ma, Jun-An

, p. 2773 - 2777 (2010)

In the presence of chiral phosphoric acid, an enantioselective Friedel-Crafts reaction of 4,7-dihydroindoles with aromatic trifluoromethyl ketones and ethyl 4,4,4-trifluoroacetoacetate has been realized. A series of 2-substituted 4,7-dihydroindoles with a trifluoromethylated tertiary alcohol moiety were obtained in 45-95% yields with 60-93% ee. Furthermore, 2-functionalized indole derivatives could be produced through a one-pot process.
