Check Digit Verification of cas no

The CAS Registry Mumber 111561-35-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,5,6 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 111561-35:
(8*1)+(7*1)+(6*1)+(5*5)+(4*6)+(3*1)+(2*3)+(1*5)=84
84 % 10 = 4
So 111561-35-4 is a valid CAS Registry Number.

Gold-Catalyzed Synthesis of Tropone and Its Analogues via Oxidative Ring Expansion of Alkynyl Quinols

Zhao, Jidong,Liu, Jun,Xie, Xin,Li, Shi,Liu, Yuanhong

, p. 5926 - 5929 (2015)

A new and convenient strategy for the synthesis of functionalized tropone derivatives based on the gold-catalyzed oxidative ring expansion of alkynyl quinols has been developed. The reaction proceeds via gold-catalyzed highly regioselective oxidation foll
