130780-27-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130780-27-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,8 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130780-27:
(8*1)+(7*3)+(6*0)+(5*7)+(4*8)+(3*0)+(2*2)+(1*7)=107
107 % 10 = 7
So 130780-27-7 is a valid CAS Registry Number.

Aryl and Allyl C-Glycosidation Methods Using Unprotected Sugars

Toshima, Kazunobu,Matsuo, Goh,Ishizuka, Toru,Ushiki, Yasunobu,Nakata, Masaya,Matsumura, Shuichi

, p. 2307 - 2313 (2007/10/03)

Practical and highly stereoselective aryl and allyl C-glycosidation methods using unprotected sugars as glycosyl donors have been developed. Aryl C-glycosidations of several unprotected 2-deoxy sugars with phenol and naphthol derivatives by the combined u

C-Arylglycosylation of Unprotected Free Sugar

Toshima, Kazunobu,Matsuo, Goh,Ishizuka, Toru,Nakata, Masaya,Kinoshita, Mitsuhiro

, p. 1641 - 1642 (2007/10/02)

Highly regio- and stereo-selective C-arylglycosylations of the protected free sugars 1-4, the unprotected methyl glycosides 6-9 and the unprotected free sugars 10 and 11 with 2-naphthol 5 are effectively realized by the combined use of TMSOTf-AgClO4 (TMSO

Efficient C-arylglycosylation of 1-O-methyl sugar by novel use of TMSOTf-AgClO4 catalyst system

Toshima,Matsuo,Tatsuta

, p. 2175 - 2178 (2007/10/02)

Highly β-stereoselective C-arylglycosylations of the 1-O-methyl sugars 1-4 with 2-naphthol (9) were effectively achieved by novel combinational use of a catalytic amount of TMSOTf-AgClO4 as an activator. Also, C-arylglycosylations of the 1-O-ac

Improvement in O -> C Glycoside Rearrangement Approach to C-Aryl Glycosides: Use of 1-O-Acetyl Sugar as Stable but Efficient Glycosyl Donor

Matsumoto, Takashi,Hosoya, Takamitsu,Suzuki, Keisuke

, p. 4629 - 4632 (2007/10/02)

1-O-Acetyl sugars serve as efficient glycosyl donor in the O -> C-glycoside rearrangement approach to C-aryl glycosides.Model study was carried out on three types of 2-deoxy-glycosyl acetates including amino sugar derivative.Comparison of the promoters, Cp2HfCl2-AgClO4, SnCl4, BF3*OEt2 is described.
