124209-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124209-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,2,0 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 124209-98:
(8*1)+(7*2)+(6*4)+(5*2)+(4*0)+(3*9)+(2*9)+(1*8)=109
109 % 10 = 9
So 124209-98-9 is a valid CAS Registry Number.

Synthesis and photochromic properties of cycloalkylidene fulgides
Lee, Wei-Woon Wayne,Gan, Leong-Ming,Loh, Teck-Peng
, p. 2473 - 2477 (2005)
A series of cycloalkylidene fulgides have been synthesized using β,γ-unsaturated diesters, instead of the usual α,β- unsaturated diesters. A study of their photochromic properties revealed that an increase in the cycloalkylidene ring size caused a subsequ
