857642-16-1 Usage
General Description
The chemical "(2S,3R,4S,5R,6R)-2-{[(2R,3S,4R,5R,6R)-4,5-dihydroxy-2-(hydroxymethyl)-6-(prop-2-yn-1-yloxy)tetrahydro-2H-pyran-3-yl]oxy}-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol" is a complex carbohydrate molecule. It consists of a six-membered ring of carbon atoms (tetrahydro-2H-pyran) with multiple hydroxyl groups attached at various positions. It also contains a prop-2-yn-1-yloxy group and a hydroxymethyl group. (2S,3R,4S,5R,6R)-2-{[(2R,3S,4R,5R,6R)-4,5-dihydroxy-2-(hydroxymethyl)-6-(prop-2-yn-1-yloxy)tetrahydro-2H-pyran-3-yl]oxy}-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol is a derivative of glucose and is likely involved in various biological processes as a component of larger carbohydrate structures. Its specific stereochemistry and functional groups make it an important building block in the synthesis of more complex carbohydrates and glycoconjugates.
Check Digit Verification of cas no
The CAS Registry Mumber 857642-16-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,6,4 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 857642-16:
(8*8)+(7*5)+(6*7)+(5*6)+(4*4)+(3*2)+(2*1)+(1*6)=201
201 % 10 = 1
So 857642-16-1 is a valid CAS Registry Number.
