825635-20-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 825635-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,5,6,3 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 825635-20:
(8*8)+(7*2)+(6*5)+(5*6)+(4*3)+(3*5)+(2*2)+(1*0)=169
169 % 10 = 9
So 825635-20-9 is a valid CAS Registry Number.

Unsymmetrical phthalocyanines with alkynyl substituents
Kalkan, Ayfer,Koca, Atif,Bayir, Zehra Altunta?
, p. 3155 - 3162 (2008/10/09)
We report on the synthesis and characterisation of unsymmetrical metallophthalocyanines (M = Zn, Ni, Co) which carry two peripheral hexylthio substituents on each of three of the benzenoid groups, while the fourth one carries two phenylethynyl groups. The
