116408-80-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116408-80-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,4,0 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 116408-80:
(8*1)+(7*1)+(6*6)+(5*4)+(4*0)+(3*8)+(2*8)+(1*0)=111
111 % 10 = 1
So 116408-80-1 is a valid CAS Registry Number.

Total synthesis of coriandrin and 7-demethylcoriandrin via a new synthesis of isocoumarins
Mal, Dipakranjan,Bandyopadhyay, Mousumi,Ghorai, Sujit K.,Datta, Kalyani
, p. 3677 - 3680 (2000)
Indenone epoxides 8, prepared from the corresponding indenones, have been shown to undergo clean thermal rearrangement to give isocoumarins 10 in high yields. This synthesis of isocoumarins, when applied to oxaindace-none 7, resulted in the total synthesis of coriandrin (1). (C) 2000 Elsevier Science Ltd.
