173526-92-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173526-92-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,5,2 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 173526-92:
(8*1)+(7*7)+(6*3)+(5*5)+(4*2)+(3*6)+(2*9)+(1*2)=146
146 % 10 = 6
So 173526-92-6 is a valid CAS Registry Number.

Li, Cong,Wong, Wing-Tak
, p. 5595 - 5601 (2007/10/03)
A general one-step synthesis for tris N-alkylated cyclens with good yield and unprecedented selectivity is presented. Tris and 1,4-bis N-alkylated cyclens, as the only two major products are isolated. Furthermore, according to the single crystal X-ray str
