16275-68-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16275-68-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,7 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 16275-68:
(7*1)+(6*6)+(5*2)+(4*7)+(3*5)+(2*6)+(1*8)=116
116 % 10 = 6
So 16275-68-6 is a valid CAS Registry Number.

Antiaromatic Carbaporphyrinoids: Fluorene as a Fused Motif toward the Synthesis of meso-Fused Heterobenziporphyrins
Kumar, Ankit,Laxman, Kandala,Ravikanth, Mangalampalli
, p. 8726 - 8730 (2019)
meso-Tetraphenyl meta-benziporphyrins are nonaromatic macrocycles which can be changed to antiaromatic by fusing the core benzene ring with one of the adjacent meso-phenyl groups, as demonstrated here by adopting a premodification method. We used a fluore
