Check Digit Verification of cas no

The CAS Registry Mumber 59749-78-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,7,4 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 59749-78:
(7*5)+(6*9)+(5*7)+(4*4)+(3*9)+(2*7)+(1*8)=189
189 % 10 = 9
So 59749-78-9 is a valid CAS Registry Number.

[Pd]-Catalyzed Intermolecular Coupling and Acid Mediated Intramolecular Cyclodehydration: One-Pot Synthesis of Indenes

Niharika, Pedireddi,Satyanarayana, Gedu

, p. 971 - 979 (2018/02/22)

An efficient one-pot synthesis of indenes from simple starting materials is presented. This process involves a dual C–C bond formation through an intermolecular Heck coupling reaction followed by acid-mediated intramolecular cyclodehydration. The strategy

Superacid-Mediated Intramolecular Cyclization/Condensation: Facile One-Pot Synthesis of Spirotetracyclic Indanones and Indenes

Ramulu, Bokka Venkat,Kumar, Devarapalli Ravi,Satyanarayana, Gedu

, p. 2179 - 2183 (2017/09/26)

A facile, superacid-promoted, domino, one-pot synthesis of novel spirotetracyclic indanones through intramolecular Friedel-Crafts acylation/alkylation of α,β-unsaturated cinnamic acid esters is presented. Interestingly, when the β-aryl group contained ele

Synthesis of indenes via aluminum chloride-promoted tandem Friedel-Crafts alkylation of arenes and cinnamaldehydes

Kheira, Haiouani,Li, Pingfan,Xu, Jiaxi

, p. 168 - 174 (2014/06/09)

A series of substituted indenes were synthesized from arenes and cinnamaldehydes via aluminum chloride-promoted tandem Friedel-Crafts alkylation. The scope and limitation of the tandem reaction were explored. A plausible reaction mechanism is also discuss
