167281-07-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 167281-07-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,2,8 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 167281-07:
(8*1)+(7*6)+(6*7)+(5*2)+(4*8)+(3*1)+(2*0)+(1*7)=144
144 % 10 = 4
So 167281-07-4 is a valid CAS Registry Number.

Internal Activation of Acrylate-Type Dienophiles in Diels-Alder Reactions
Kan, Toshiyuki,Ohfune, Yasufumi
, p. 943 - 946 (1995)
Diels-Alder reactions of less reactive acrylate-type dienophiles with dienes were achieved by replacing its ester counterpart to a pentafluorophenyl group, which remarkably enhanced the reactivity of the dienophiles to give the corresponding cycloadducts
