Check Digit Verification of cas no
The CAS Registry Mumber 53143-77-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,1,4 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 53143-77:
(7*5)+(6*3)+(5*1)+(4*4)+(3*3)+(2*7)+(1*7)=104
104 % 10 = 4
So 53143-77-4 is a valid CAS Registry Number.

Temperature Dependence of Linear Free Energy Relationship of Carbene Cycloadditions
Giese, Bernd,Lee, Woo-Bung
, p. 3306 - 3312 (2007/10/02)
Cycloadditions of carbenes 1 with alkenes 2-5 at 293 K are described by equation (a).Measurements of selectivities at 333 and 393 K (Table 1) show that this linear free energy relationship depends upon temperature.A variation of the reaction temperature has no influence on mesomeric interactions, but influences the inductive effects.From equations (a), (b) and (c) it can be concluded that the selectivity of carbenes with substituents of weak electron withdrawing ability increases with increasing temperature.
