41341-82-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 41341-82-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,3,4 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 41341-82:
(7*4)+(6*1)+(5*3)+(4*4)+(3*1)+(2*8)+(1*2)=86
86 % 10 = 6
So 41341-82-6 is a valid CAS Registry Number.

Concise and practical route to tri- and tetra-hydroxy seven-membered iminocyclitols as glycosidase inhibitors from d-(+)-glucurono-γ-lactone

Kalamkar, Navnath B.,Kasture, Vijay M.,Chavan, Sanjay T.,Sabharwal, Sushma G.,Dhavale, Dilip D.

, p. 8522 - 8526 (2010)

An efficient and short total synthesis of tetrahydroxy-1c and trihydroxy-azepane 1d is reported in 72% and 57% overall yields, respectively, from d-(+)-glucurono-γ-lactone. Thus, d-glucuronolactone 2 on acetonide protection, DIBAL-H reduction and one-pot intermolecular reductive amination followed by -NCbz protection afforded 6-(N-benzyl-N-benzyloxycarbonyl) amino-6-deoxy-1,2-O-isopropylidene-α-d-gluco-1,4-furanose 5a. 1,2-Acetonide hydrolysis in 5a and Pd-mediated intramolecular reductive aminocyclization afforded tetrahydroxyazepane 1c. An analogous pathway with 5-deoxy-1,2-O-isopropylidene-α-d-glucurono-6,3-lactone 3b gave trihydroxy-azepane 1d. Glycosidase inhibitory activity of 1c/1d was studied and 1d was found to be potent inhibitor of α-mannosidase and β-galactosidase.
