158953-96-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 158953-96-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,9,5 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 158953-96:
(8*1)+(7*5)+(6*8)+(5*9)+(4*5)+(3*3)+(2*9)+(1*6)=189
189 % 10 = 9
So 158953-96-9 is a valid CAS Registry Number.

Acid-catalyzed acylation reaction via C-C bond cleavage: A facile and mechanistically defined approach to synthesize 3-acylindoles

Xing, Qi,Li, Pan,Lv, Hui,Lang, Rui,Xia, Chungu,Li, Fuwei

, p. 12181 - 12184 (2014)

A facile acid-catalyzed acylation of indoles with 1,3-dione as an eco-friendly acylating agent was developed. This protocol combines C-C bond cleavage and heterocyclic C-H bond functionalization to form new C-C bonds. Based on the detailed mechanistic studies, a credible mechanistic pathway was proposed.
