197716-38-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 197716-38-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,7,1 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 197716-38:
(8*1)+(7*9)+(6*7)+(5*7)+(4*1)+(3*6)+(2*3)+(1*8)=184
184 % 10 = 4
So 197716-38-4 is a valid CAS Registry Number.

Iodine monochloride (ICl) as a highly efficient, green oxidant for the oxidation of alcohols to corresponding carbonyl compounds

Wei, Peng,Zhang, Datong,Gao, Zhigang,Cai, Wenqing,Xu, Weiren,Tang, Lida,Zhao, Guilong

, p. 1457 - 1470 (2015/05/20)

Iodine monochloride (ICl) was discovered to be a highly efficient, green oxidant, which can oxidize aldose hemiacetals, diarylmethanols, arylalkylmethanols, anddialkylmethanols to the corresponding aldose lactones, diarylmethanones, arylalkylmethanones, and dialkylmethanones, respectively, in high yields. ICl as a green, metal-free oxidant is characterized by mild reaction condition, short reaction time, good yield, and broad scope.

An olefin metathesis route for the preparation of (1 → 6)-linked C-disaccharide glycals. A convergent and flexible approach to C-saccharide synthesis

Postema, Maarten H. D.,Calimente, Daniel,Liu, Lei,Behrmann, Tonja L.

, p. 6061 - 6068 (2007/10/03)

A convergent route to a variety of C-1-disaccharide glycals based on the olefin metathesis reaction of enol ethers and alkenes is described. The DCC-mediated coupling reaction of a variety of pentose enitols (1a-c) with a number of C-5- and C-6-monosaccharide carboxylic acids (2a-e) gave the corresponding esters 3a-1 in good yield. Methylenation of these compounds was followed by ring-closing metathesis, mediated by the Schrock molybdenum catalyst 8 in warm toluene, to provide the target C-disaccharide glycals 5a-1. The formed enol ether double bond in 5a was then transformed, via standard manipulations, into a variety of C-disaccharide derivatives 21-25.

Novel asymmetric synthesis of an indolizidine alkaloid, (+)-lentiginosine employing highly stereoselective hydrogenation of α-hydroxypyrrolidine

Yoda, Hidemi,Kawauchi, Miho,Takabe, Kunihiko

, p. 137 - 138 (2007/10/03)

An efficient and novel process is described for the asymmetric synthesis of a (1S,2S,8aS)-dihydroxyindolizidine alkaloid, (+)-lentiginosine in which the asymmetric deoxygenation of the quaternary α-hydroxypyrrolidine derivative derived from D-xylose is used as a key step.
