23353-88-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23353-88-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,3,5 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 23353-88:
(7*2)+(6*3)+(5*3)+(4*5)+(3*3)+(2*8)+(1*8)=100
100 % 10 = 0
So 23353-88-0 is a valid CAS Registry Number.

Synthesis of fluorene- and spirobifluorene-fused thiophenes
Yao, Wen,Liu, Qiancai,Shi, Yingbo,Tang, Jie
, p. 1077 - 1088 (2012/07/28)
A novel synthetic route to fluorene- and spirobifluorene-fused thiophenes is explored by starting with ninhydrin. The Diels-Alder cycloaddition was employed to construct the key intermediate, 2,3-bis(hydroxymethyl)-1,4-diphenyl- fluorenone, which was furt
