74469-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74469-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,6 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74469-97:
(7*7)+(6*4)+(5*4)+(4*6)+(3*9)+(2*9)+(1*7)=169
169 % 10 = 9
So 74469-97-9 is a valid CAS Registry Number.

Synthesis of Benzene Derivatives with Several Homochirally-analogous Substituents
Schoenfelder, Wolfgang,Snatzke, Guenther
, p. 1855 - 1866 (2007/10/02)
By cyclotrimerization of the corresponding acetylene derivatives some 1,3,5-trisubstituted benzene derivatives (2a - c, 8a, d) containing three identical chiral groups have been synthesized.The analogous mono- and 1,4-disubstituted products (6, 7) have be
