Check Digit Verification of cas no

The CAS Registry Mumber 438568-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,8,5,6 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 438568-71:
(8*4)+(7*3)+(6*8)+(5*5)+(4*6)+(3*8)+(2*7)+(1*1)=189
189 % 10 = 9
So 438568-71-9 is a valid CAS Registry Number.

Unsymmetrical O-bridged calixarenes derived from tBu-calix[4]arene and p-benzylcalix[4]arene

Makha, Mohamed,Nichols, Peter J.,Hardie, Michaele J.,Raston, Colin L.

, p. 354 - 359 (2007/10/03)

Bis-calixarenes derived from linking p-tBu-calix[4]arene with p-tBu-calix[n]arenes (n = 5, 8) via ethylene linkages have been prepared and structural authentication in the solid state for the compound with p-tBu-calix[4]arene linked to p-tBu-calix[5]arene has been carried out. The bis-calixarene derived from linking p-tBu-calix[4]arene with p-benzylcalix[4]arene and its related chemistry are also reported.
