877869-07-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 877869-07-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,7,8,6 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 877869-07:
(8*8)+(7*7)+(6*7)+(5*8)+(4*6)+(3*9)+(2*0)+(1*7)=253
253 % 10 = 3
So 877869-07-3 is a valid CAS Registry Number.

Phenanthroline dicarboxamide-based helical foldamers: Stable helical structures in methanol
Hu, Zhi-Qiang,Hu, Hai-Yu,Chen, Chuan-Feng
, p. 1131 - 1138 (2007/10/03)
A series of new aromatic oligoamides 2-5 based on 1,10-phenanthroline diacid and o-phenylenediamine have been synthesized through a convergent segment coupling strategy. These oligomers can fold into well-defined helical structures in solution through int
