Check Digit Verification of cas no

The CAS Registry Mumber 1124225-72-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,4,2,2 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1124225-72:
(9*1)+(8*1)+(7*2)+(6*4)+(5*2)+(4*2)+(3*5)+(2*7)+(1*2)=104
104 % 10 = 4
So 1124225-72-4 is a valid CAS Registry Number.

Highly regio-and stereoselective one-pot synthesis of carbohydrate-based butyrolactones

Yousuf, Syed Khalid,Mukherjee, Debaraj,L, Mallikharjunrao,Taneja, Subhash C.

supporting information; experimental part, p. 576 - 579 (2011/04/23)

The use of manganese(III) acetate allows the direct synthesis of diverse arrays of [4.3.0] bicyclic carbohydrate-based γ-lactone building blocks from glycals. A mechanism to explain the high regio-and stereoselectivity is proposed. The new reaction has th

Stereoselective diversity-oriented syntheses of functionalized saccharides from bicyclic carbohydrate 1,2-lactones

Yin, Jian,Linker, Torsten

experimental part, p. 2447 - 2461 (2011/04/26)

Bicyclic carbohydrate 1,2-lactones have been synthesized in only two steps and high yields by saponification and subsequent cyclization from known malonate addition products to glycals. The gluco-configured lactone serves as an important precursor for div

Convenient synthesis of bicyclic carbohydrate 1,2-lactones and their stereoselective opening to 1-functionalized glucose derivatives

Yin, Jian,Linker, Torsten

supporting information; experimental part, p. 49 - 52 (2009/06/28)

The convenient synthesis of lactone compounds and their stereoselective transformations by reactions with nucleophiles was reported. The method is applicable for unsaturated hexoses, pentoses, and disaccharide's, and is characterized by high yields and stereoselectivities. The release of carbon dioxide and methanol provides the driving force of the reaction, which favors the lactonization entropically. A convenient and general entry to bicycle carbohydrate 1,2-lactones in only three steps from glycals was developed. The opening of the gluco-configured lactone was demonstrated with various nucleophiles, which enabled the introduction of hetero and carbon substituents at the anomeric position.
