Check Digit Verification of cas no

The CAS Registry Mumber 133871-46-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,7 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 133871-46:
(8*1)+(7*3)+(6*3)+(5*8)+(4*7)+(3*1)+(2*4)+(1*6)=132
132 % 10 = 2
So 133871-46-2 is a valid CAS Registry Number.

13C NMR Chemical Shifts. A Single Rule To Determine the Conformation of Calixarenes

Jaime, Carlos,Mendoza, Javier de,Prados, Pilar,Nieto, Pedro M.,Sanchez, Concha

, p. 3372 - 3376 (2007/10/02)

The conformations of calixarenes can be deduced from the 13C NMR chemical shift of the methylene groups connecting each pair of aromatic rings.Inspection of 24 cases revealed that when the phenol rings beside each methylene are in a syn orientation (i.
