Check Digit Verification of cas no

The CAS Registry Mumber 83497-33-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,9 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83497-33:
(7*8)+(6*3)+(5*4)+(4*9)+(3*7)+(2*3)+(1*3)=160
160 % 10 = 0
So 83497-33-0 is a valid CAS Registry Number.

Studies of the Mechanistic Diversity of Sodium Cyanoborohydride Reduction of Tosylhydrazones

Miller, Vaughn P.,Yang, Ding-yah,Weigel, Theresa M.,Han, Oksoo,Liu, Hung-wen

, p. 4175 - 4188 (2007/10/02)

Reduction of tosylhydrazone derivatives of ketones and aldehydes with sodium cyanoborohydride in acidic medium is a mild, albeit versatile, deoxygenation reaction.The reaction mechanism has been proposed to proceed via either a direct hydride attack route or a tautomerization-then-reduction route.By using a mild reduction procedure (NaBH3CN, THF-MeOH, 0 deg C), it has been possible to stop the deoxygenation halfway and isolate the nascent tosylhydrazine product.Characterization of the resulting hydrazine to define the origin of the hydrogen being delivered to theformer carbonyl carbon has allowed us to unambiguously distinguish between these two possible mechanisms.Studies of reduction of tosylhydrazones derived from conjugated and saturated ketones confirmed earlier speculation that these reductions occur through a direct hydride attack mechanism.The reduction of para-substituted methyl phenyl ketone tosylhydrazones revealed a competition between these two mechanisms.Substrates bearing electron-donating substituents prefer to direct hydride attack pathway, while those with electron-withdrawing substituents favor an initial tautomerization prior to reduction.Sugar and hydroxyl ketone tosylhydrazones are also reduced by competing mechanisms.The mechanistic diversity in those cases may be attributed to the inductive effects compelled by the α substituents and the conformational constraints imposed by the ring structure.The mechanistic insights gained from these studies indicate that the direct hydride attack mechanism is the main reaction pathway due to the propensity of NaBH3CN to selectively attack the iminium ion.The tautomerization-then-reduction mechanism prevails only when the tautomerization of hydrazon to azohydrazine is facilitated.

BRANCHED-CHAIN SUGARS. XXXV. THE SYNTHESIS OF L-RUBRANITROSE (2,3,6-TRIDEOXY-3-C-METHYL-4-O-METHYL-3-NITRO-L-XYLO-HEXOPYRANOSE).

Yoshimura,Yasumori,Kondo,Sato

, p. 2535 - 2537 (2007/10/02)

The compound was stereoselectively synthesized from methyl 2,6-dideoxy-4-O-methyl- beta -L-threo-hexopyranosid-3-ulose through the successive conversions; cyanomesylation, reductive spiro aziridine formation, reductive ring-opening to the methyl-branched amino sugar, oxidation to the corresponding nitro sugar.
