128825-67-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128825-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,2 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128825-67:
(8*1)+(7*2)+(6*8)+(5*8)+(4*2)+(3*5)+(2*6)+(1*7)=152
152 % 10 = 2
So 128825-67-2 is a valid CAS Registry Number.

, p. 2133 - 2136 (2007/10/02)
Unssymetrically quinone-substituted porphyrin dimers were synthesized.The fluorescence of the both porphyrins in these models was effectively quenched by the attached quinone.
