118520-80-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118520-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,5,2 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118520-80:
(8*1)+(7*1)+(6*8)+(5*5)+(4*2)+(3*0)+(2*8)+(1*0)=112
112 % 10 = 2
So 118520-80-2 is a valid CAS Registry Number.

Lactonization of 2-Alkynylbenzoates for the Assembly of Isochromenones Mediated by BF3·Et2O

Zhang, Xiang,Wan, Xintong,Cong, Ying,Zhen, Xiaohua,Li, Qiao,Zhang-Negrerie, Daisy,Du, Yunfei,Zhao, Kang

, p. 10402 - 10411 (2019/08/20)

A general and efficient lactonization method of readily available 2-alkynylbenzoates affording biologically important isochromenones has been realized via a solely BF3·Et2O-mediated 6-endo-dig cyclization process under mild condition

Organomercury Mediated Synthesis of Isocoumarins

Nagarajan, A.,Balasubramanian, Tiruvenkat R.

, p. 917 - 919 (2007/10/02)

A facile and convenient synthesis of isocoumarins via an organomercurial route is reported.The synthesis involves reaction of methyl 2-alkynbenzoates with mercuric acetate to give the corresponding isocoumarin mercurials which serve as intermediates to afford the appropriate isocoumarins having substituents as Cl,I,Br,COCH3 etc.
