212626-87-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 212626-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,6,2 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 212626-87:
(8*2)+(7*1)+(6*2)+(5*6)+(4*2)+(3*6)+(2*8)+(1*7)=114
114 % 10 = 4
So 212626-87-4 is a valid CAS Registry Number.

Copper-catalyzed domino coupling reaction: An efficient method to synthesize oxindoles

Hsieh, Jen-Chieh,Cheng, An-Yi,Fu, Jun-Hao,Kang, Ting-Wei

supporting information; experimental part, p. 6404 - 6409 (2012/09/05)

An efficient and novel procedure for a copper catalyzed domino coupling reaction has been developed, which afforded various oxindoles in good to excellent yields with tolerance of various substituents. In addition, this method could be applied to synthesize horsfiline and coerulescine in few steps with high total yields. The Royal Society of Chemistry 2012.
