438526-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 438526-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,8,5,2 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 438526-19:
(8*4)+(7*3)+(6*8)+(5*5)+(4*2)+(3*6)+(2*1)+(1*9)=163
163 % 10 = 3
So 438526-19-3 is a valid CAS Registry Number.

Dendron rodcoils: Synthesis of novel organic hybrid structures
Zubarev, Eugene R.,Stupp, Samuel I.
, p. 5762 - 5773 (2007/10/03)
Convergent and divergent syntheses of novel organic hybrid structures termed dendron rodcoils (DRC) containing dendritic, rodlike, and coillike segments are described. The aryl ester dendron masked with 32 trifluoromethyl groups is prepared via a converge
