344951-14-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344951-14-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,9,5 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 344951-14:
(8*3)+(7*4)+(6*4)+(5*9)+(4*5)+(3*1)+(2*1)+(1*4)=150
150 % 10 = 0
So 344951-14-0 is a valid CAS Registry Number.

Facile synthesis of a selectively protected triazamacrocycle
Skerlj, Renato T.,Nan, Siqiao,Zhou, Yuanxi,Bridger, Gary J.
, p. 7569 - 7571 (2007/10/03)
1,7-Diaminoheptane was selectively homologated with the novel reagent N-(2-nitrobenzenesulfonyl)aziridine. A series of reactions then followed to afford a selectively protected 14-membered triazamacrocyclic ring.
