749858-85-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 749858-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,8,5 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 749858-85:
(8*7)+(7*4)+(6*9)+(5*8)+(4*5)+(3*8)+(2*8)+(1*5)=243
243 % 10 = 3
So 749858-85-3 is a valid CAS Registry Number.

Rapid oligosaccharide synthesis using a fluorous protective group

Miura, Tsuyoshi,Goto, Kohtaro,Waragai, Hideki,Matsumoto, Hiroharu,Hirose, Yuriko,Ohmae, Masashi,Ishida, Hide-Ki,Satoh, Ai,Inazu, Toshiyuki

, p. 5348 - 5353 (2004)

The Bfp-OH, a novel fluorous protecting reagent, was able to be easily prepared. The Bfp group was readily introduced to a carbohydrate, removed in high yield, and recyclable after cleavage. The use of the Bfp group made it possible to synthesize a pentasaccharide by minimal column chromatography purification. Each synthetic intermediate was able to be easily purified only by simple fluorous-organic solvent extraction and monitored by TLC, NMR, and MS.
