174138-05-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174138-05-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,1,3 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 174138-05:
(8*1)+(7*7)+(6*4)+(5*1)+(4*3)+(3*8)+(2*0)+(1*5)=127
127 % 10 = 7
So 174138-05-7 is a valid CAS Registry Number.

A General Synthesis of Mono- and Disubstituted 1,4,7-Triazacyclononanes
Kovacs, Zoltan,Sherry, A. Dean
, p. 9269 - 9272 (2007/10/02)
1,4,7-Triazacyclononane reacts selectively with 2-(t-butoxycarbonyloxyimino)- and 2-(benzyloxycarbonyloxyimino)-2-phenylacetonitrile to give 1,4-diprotected derivatives which could be converted to mono and disubstituted triazacyclononanes.
