Check Digit Verification of cas no

The CAS Registry Mumber 96278-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,2,7 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 96278-02:
(7*9)+(6*6)+(5*2)+(4*7)+(3*8)+(2*0)+(1*2)=163
163 % 10 = 3
So 96278-02-3 is a valid CAS Registry Number.

Design and synthesis of two aromatic amines with dendritic structure

Luo, Zhenghong,Cheng, Hua,Xu, Wei

experimental part, p. 303 - 308 (2010/10/21)

The design and synthesis of two aromatic amines with dendritic structures, i.e. 3,4,5-tribenzyloxyaniline (3,4,5-G1-NH2) and 2,5-dibenzyloxyaniline (2,5-G1-NH2), were conducted. A coupling reaction of three or two equivalents of benzyl bromide to one equivalent of methyl hydroxybenzoate generated methyl 3,4,5-tribenzyloxybenzoate (3,4,5-G1-COOCH3), methyl 2,5-dibenzyloxybenzoate (2,5-G1-COOCH3) and 2,6-dibenzyloxybenzoate (2,6-G1-COOCH3) in high yields. All G1-COOCH3 derivatives were studied by X-ray analysis. The results show that these dendrons have sufficient volume to be used as the fine ligands for certain catalysts. The amide intermediates (benzamide, G1-CONH2) were obtained by reaction between ammonia and G1-COOCH3. Interestingly, 2,6-dibenzyloxybenzamide (2,6-G1-CONH2) can not be prepared in the same condition, which may be due to the overlarge steric block. Sodium hypochlorite was an effective oxidant to generate methyl carbamates G1-NHCO2CH3.
