107323-63-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107323-63-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,3,2 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 107323-63:
(8*1)+(7*0)+(6*7)+(5*3)+(4*2)+(3*3)+(2*6)+(1*3)=97
97 % 10 = 7
So 107323-63-7 is a valid CAS Registry Number.

Cyclization of 4-Hydroxy-(E)-2-alkenoic Esters: Simple Synthesis of Butenolides
Tanikaga, Rikuhei,Yamashita, Hiroshi,Kaji, Aritsune
, p. 416 - 417 (2007/10/02)
Simple treatment of 4-hydroxy-(E)-2-alkenoic esters with benzenethiol leads to cyclization to give 3-phenylthio-4-alkanolides, which are easily converted into 3-phenylthio-2-alken-4-olides and 2-alken-4-olides (Δα,β-butenolides).
