871734-70-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871734-70-2 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, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 871734-70:
(8*8)+(7*7)+(6*1)+(5*7)+(4*3)+(3*4)+(2*7)+(1*0)=192
192 % 10 = 2
So 871734-70-2 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
