730985-74-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 730985-74-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,0,9,8 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 730985-74:
(8*7)+(7*3)+(6*0)+(5*9)+(4*8)+(3*5)+(2*7)+(1*4)=187
187 % 10 = 7
So 730985-74-7 is a valid CAS Registry Number.

Single-crystalline photochromism of a diarylethene dimer
Kobatake, Seiya,Kuma, Shunpei,Irie, Masahiro
, p. 945 - 951 (2007/10/03)
A fluorene derivative having two diarylethene units at the 9,9′-positions was synthesized, and the photochromic behavior was examined in a single-crystalline phase as well as in solution. Upon irradiation with ultraviolet light (Λ = 313 nm), a hexane solu
