Check Digit Verification of cas no

The CAS Registry Mumber 1610529-96-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,0,5,2 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1610529-96:
(9*1)+(8*6)+(7*1)+(6*0)+(5*5)+(4*2)+(3*9)+(2*9)+(1*6)=148
148 % 10 = 8
So 1610529-96-8 is a valid CAS Registry Number.

Synthetic routes towards fluorine-containing amino sugars: Synthesis of fluorinated analogues of tomosamine and 4-amino-4-deoxyarabinose

Albler, Christopher,Schmid, Walther

, p. 2451 - 2459 (2014)

Fluorinated analogues of bioactive amino sugars are of high interest in medicinal chemistry. We developed a straightforward synthetic route towards this class of carbohydrates by applying a titanium-mediated aldol addition. Thus, two-carbon chain elongations of serine- and threonine-derived aldehydes with a chiral fluoroacetyl-oxazolidinone could be achieved in good yields and excellent diastereoselectivities to generate a fluorohydrin-containing carbon skeleton. A short deprotection sequence subsequently furnished the pyranoid forms of various 4-amino-2-fluoropentoses and -hexoses, respectively. The versatility of this strategy was demonstrated by the stereoselective synthesis of naturally abundant 4-amino-4-deoxyarabinose and 4-amino-4,6-dideoxygalactose (tomosamine). 4-Amino-2-fluoropentoses and -hexoses were prepared through two-carbon chain elongations by Ti-mediated aldol additions of serine- and threonine-derived amino aldehydes to fluoroacetyl-ephedrine-oxazolidinone. Excellent stereoselectivities were attained for matched-case fluorohydrins, which were deprotected in a short sequence. Copyright
