52251-19-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52251-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,2,5 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52251-19:
(7*5)+(6*2)+(5*2)+(4*5)+(3*1)+(2*1)+(1*9)=91
91 % 10 = 1
So 52251-19-1 is a valid CAS Registry Number.

Strong overcrowding in dimethyl 2-(dimethyl-amino)terephthalate

Centore, Roberto,Fusco, Sandra,Peluso, Andrea,Carotenuto, Maurizio,Tuzi, Angela

, p. o420-o422 (2008)

The mol-ecular structure of the title compound, C12H15NO4, has several features related to steric hindrance due to the ester and dimethyl-amine groups being located ortho with respect to one another. In particular, the carbonyl group of the ester is not coplanar with the ring, the amine N atom is in a pyramidal arrangement [the N atom is 0.2161 (12) A from the three C atoms to which it is bonded] and the C atom of the adjacent ester group lies 0.3784 (14) A out of the plane of the aromatic ring. The deformations found in the X-ray structure have been confirmed by ab initio quantum mechanical calculations.

Synthesis of secondary and tertiary amine-containing MOFs: C-N bond cleavage during MOF synthesis

Hahm, Hyungwoo,Ha, Hyeonbin,Kim, Seongmin,Jung, Byunghyuck,Park, Myung Hwan,Kim, Youngjo,Heo, Jungseok,Kim, Min

, p. 5644 - 5650 (2015/08/03)

Secondary and tertiary amine-containing metal-organic frameworks (MOFs) have been synthesized, and unprecedented C-N bond cleavage phenomena were observed during MOF formation. Utilizing the secondary amine-containing ligand (BDC-NHMe), three new MOFs hav
