749257-26-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 749257-26-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,2,5 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 749257-26:
(8*7)+(7*4)+(6*9)+(5*2)+(4*5)+(3*7)+(2*2)+(1*6)=199
199 % 10 = 9
So 749257-26-9 is a valid CAS Registry Number.

Synthesis of 2,8-disubstituted analogues of Troeger's base
Kiehne, Ulf,Luetzen, Arne
, p. 1687 - 1695 (2004)
Starting from the 2,8-dibromo- and the 2,8-diiodo-substituted Troeger's base analogues 1 and 2, several new symmetrically disubstituted derivatives 4, 5, and 7-17 could be obtained by transition metal-catalyzed cross-coupling reactions or other functional
