16628-25-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16628-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,2 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 16628-25:
(7*1)+(6*6)+(5*6)+(4*2)+(3*8)+(2*2)+(1*5)=114
114 % 10 = 4
So 16628-25-4 is a valid CAS Registry Number.

Two efficient N-acylation methods mediated by solid-supported reagents for weakly nucleophilic heterocyclic amines

Kim, Kyungjin,Le, Kang

, p. 1957 - 1959 (1999)

Two efficient acylation methods utilizing solid-supported reagents have been developed for weakly nucleophilic heterocyclic amines. The novel approaches by chemoselective purification and polymeric-supported reagents facilitate library synthesis of divers

On Water: Metal-Free Synthesis of Highly Functionalized Benzothiazolylidene from ortho-Haloanilines

Saini, Kapil Mohan,Saunthwal, Rakesh K.,Kumar, Shiv,Verma, Akhilesh K.

, p. 2689 - 2698 (2019/03/15)

An environmentally benign, transition-metal-free organic base promoted one-pot cascade synthesis of highly functionalized benzo[d]thiazol-2(3H)-ylidene benzamide in the presence of water was accomplished by three-component reaction of ortho-iodoanilines,

Identification of small-molecule inhibitors of the Aβ-ABAD interaction

Xie, Yuli,Deng, Shixian,Chen, Zhenzhang,Yan, Shidu,Landry, Donald W.

, p. 4657 - 4660 (2007/10/03)

The interaction of amyloid beta peptide (Aβ) and Aβ-binding alcohol dehydrogenase (ABAD) was recently implicated in the pathogenesis of Alzheimer's disease (AD). Using an ELISA-based screening assay, we identified frentizole, an FDA-approved immunosuppressive drug, as a novel inhibitor of the Aβ-ABAD interaction. Analysis of the frentizole structure-activity relationship led to identification of a novel benzothiazole urea with a 30-fold improvement in potency.
