521970-04-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 521970-04-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,1,9,7 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 521970-04:
(8*5)+(7*2)+(6*1)+(5*9)+(4*7)+(3*0)+(2*0)+(1*4)=137
137 % 10 = 7
So 521970-04-7 is a valid CAS Registry Number.

Synthesis and quantitative structure-activity relationships of N-(1- benzylpiperidin-4-yl)phenylacetamides and related analogues as potent and selective σ1 receptor ligands

Huang, Yunsheng,Hammond, Philip S.,Whirrett, Brian R.,Kuhner, Ross J.,Wu, Li,Childers, Steven R.,Mach, Robert H.

, p. 2361 - 2370 (2007/10/03)

A series of N-(1-benzylpiperidin-4-yl)phenylacetamide derivatives was synthesized and evaluated for affinity at σ1 and σ2 receptors. Most of these compounds showed a high affinity for σ1 receptors and a low to moderate aff

Enzymatic Preparation of Optically Active Cyanohydrin Acetates

Almsick, Andreas van,Buddrus, Joachim,Hoenicke-Schmidt, Petra,Laumen, Kurt,Schneider, Manfred P.

, p. 1391 - 1393 (2007/10/02)

A series of cyanohydrin acetates (1)-(47) of widely varying structures, potential chiral building blocks for numerous synthetic applications, has been prepared in good chemical and often high optical yields by enzymatic hydrolysis of their racemic acetates in the presence of an ester hydrolase from Pseudomonas sp.
