Check Digit Verification of cas no

The CAS Registry Mumber 140404-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,4,0 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 140404-39:
(8*1)+(7*4)+(6*0)+(5*4)+(4*0)+(3*4)+(2*3)+(1*9)=83
83 % 10 = 3
So 140404-39-3 is a valid CAS Registry Number.

Development of a Novel Pathway To Access 6-Deoxy-6,6,6-trifluorosugars via 1,2-Migration of a tert-Butyldimethylsilyl Group

Yamazaki, Takashi,Mizutani, Kenji,Kitazume, Tomoya

, p. 4346 - 4359 (1993)

Trifluoromethylated furanols 2 were enzymatically resolved into the corresponding optically active forms in a highly efficient manner and were further converted to the synthetically useful 2-butenolides 6.Introduction of substituents into these butenolides 6 or their saturated lactone forms 8 was realized by boron trifluoride-mediated Michael addition of cuprates or by capture of the enolates with various kinds of electrophiles, respectively, both of which proceeded with a high degree of diastereoselectivity.Moreover, novel synthetic routes to access 6-deoxy-6,6,6-trifluorosugars were developed by utilization of 1,2-silyl migration as a key step, which was qualitatively supported by PM3 molecular orbital calculation.

Diastereoselective trifluoromethylation of chiral imide enolates with iodotrifluoromethane mediated by triethylborane

Iseki,Nagai,Kobayashi

, p. 961 - 974 (2007/10/02)

The trifluoromethylation of lithium enolates of chiral N-acyloxazolidinones with iodotrifluoromethane mediated by triethylborane proceeds with good diastereomeric excess.

Chiral Trifluoromethylated 2-Butenolides for the Construction of 6-Deoxy-6,6,6-trifluorosugars

Yamazaki, Takashi,Mizutani, Kenji,Takeda, Mitsunori,Kitazume, Tomoya

, p. 55 - 57 (2007/10/02)

Optically active 2-butenolides with a trifluoromethyl (CF3) group are synthesized via enzymatic optical resolution and are selectively transformed into 6,6,6-trifluororhodinose and amicetose by base-promoted 1,2-migration of a tert-butyldimethylsilyl moiety in a highly efficient manner.
