916803-96-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 916803-96-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,8,0 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 916803-96:
(8*9)+(7*1)+(6*6)+(5*8)+(4*0)+(3*3)+(2*9)+(1*6)=188
188 % 10 = 8
So 916803-96-8 is a valid CAS Registry Number.

Structural modification of unsymmetrically substituted monophthalocyanines by nucleophilic reactions
Tolbin,Tomilova,Zefirov
, p. 2099 - 2103 (2007/10/03)
New 2-nitro-substituted phthalocyanine zinc complexes were synthesized. The nucleophilic substitution of the NO2 group was used for the first time for the structural modification of unsymmetrically substituted monophthalocyanines. The electroni
