74458-79-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74458-79-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,5 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74458-79:
(7*7)+(6*4)+(5*4)+(4*5)+(3*8)+(2*7)+(1*9)=160
160 % 10 = 0
So 74458-79-0 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
