Check Digit Verification of cas no
The CAS Registry Mumber 1119-73-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,1 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1119-73:
(6*1)+(5*1)+(4*1)+(3*9)+(2*7)+(1*3)=59
59 % 10 = 9
So 1119-73-9 is a valid CAS Registry Number.

Page/Page column 32, (2012/06/30)
A method which comprises contacting the cyclohexene ring containing compounds having carboxylate derivatives at the 1 and 4, and optionally the 2, positions with one or more dehydrogeoation catalysts, optionally in the presence of one or more oxidants, in a continuous flow mode under conditions such that compounds containing an aromatic ring with carboxylate derivatives at the 1. and 4 positions, and optionally the 2 position, are prepared. The invention also relates to such compounds derived from starting materials derived from renewable resources.
