Check Digit Verification of cas no

The CAS Registry Mumber 88537-44-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,5,3 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 88537-44:
(7*8)+(6*8)+(5*5)+(4*3)+(3*7)+(2*4)+(1*4)=174
174 % 10 = 4
So 88537-44-4 is a valid CAS Registry Number.

Synthesis of meta,meta-Bridged Biaryls (-Metacyclophanes) via Aryl-Aryl Coupling: Factors affecting the Cyclisation

Mohamed, Salah E.N.,Whiting, Donald A.

, p. 2577 - 2582 (2007/10/02)

Two bis(iodoaryl)heptanoids (28) and (33), the iodoarylbutyl iodoarylpropyl sulphide (39), and the corresponding sulphone (40) have been prepared, and each treated with tetrakis(triphenylphosphine)nikel(0).Two new m,m-bridged biaryls (29) (31percent) and (34) (49percent) were obtained; the sulphur compounds were deiodinated in preference to coupling.These reactions are compared with those used previously in myricanol synthesis and the factors affecting ring closure are discussed.Steric effects at the coupling sites appear more important in determining product yield than torsional strain in the products.
