1384864-46-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1384864-46-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,4,8,6 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1384864-46:
(9*1)+(8*3)+(7*8)+(6*4)+(5*8)+(4*6)+(3*4)+(2*4)+(1*6)=203
203 % 10 = 3
So 1384864-46-3 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
