871734-64-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871734-64-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,7,3 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 871734-64:
(8*8)+(7*7)+(6*1)+(5*7)+(4*3)+(3*4)+(2*6)+(1*4)=194
194 % 10 = 4
So 871734-64-4 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 (2007/10/03)
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
