Check Digit Verification of cas no
The CAS Registry Mumber 56820-58-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,8,2 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 56820-58:
(7*5)+(6*6)+(5*8)+(4*2)+(3*0)+(2*5)+(1*8)=137
137 % 10 = 7
So 56820-58-7 is a valid CAS Registry Number.

A series of 5-phenyl-3-ureidobenzazepin-2-one cholecystokinin-B (CCK-B) receptor antagonists was synthesized using Beckmann ring expansion of a suitable 4-phenyl-1-tetralone as a key step. Structure-activity relationship studies revealed the importance of
ARYNIC SPECIES; EFFECT OF SUBSTITUENTS ON THE REACTIVITY OF MONOSUBSTITUTED DEHYDROBENZENES
Gavina, F.,Luis, S. V.,Costero, A. M.
, p. 155 - 166 (2007/10/02)
Evidence is presented demonstrating the existence of free dehydrobenzenes in the thermal decomposition of diaryliodonium-2-carboxylates, and that o-benzyne itself and its 4-methyl-, 4-chloro-, 4-bromo- and 4-nitro-derivatives are generated from insoluble polymer-bound precursors and trapped by a second solid phase in Diels-Alder reactions.Lifetimes for these elusive species are determined.
