253866-88-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 253866-88-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,8,6 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 253866-88:
(8*2)+(7*5)+(6*3)+(5*8)+(4*6)+(3*6)+(2*8)+(1*8)=175
175 % 10 = 5
So 253866-88-5 is a valid CAS Registry Number.

Synthesis of (+)-muricatacin and a formal synthesis of CMI-977 from l -malic acid

Gonzalez, Maria,Gandara, Zoila,Martinez, Andrea,Gomez, Generosa,Fall, Yagamare

supporting information, p. 1693 - 1700 (2013/07/27)

A total synthesis of (+)-muricatacin and a formal synthesis of CMI-977 have been achieved using commercially available l-malic acid based on our furan approach to oxacyclic systems, the proven scope of which is thus broadened. Georg Thieme Verlag Stuttgart, New York.

Stereoselective syntheses of pharmaceutically relevant chiral tetrahydrofurans from (S)- and (R)-glyceraldehyde derivatives

Sharma,Punna, Sreenivas,Rajendra Prasad,Krishna, Palakodety Radna,Chorghade, Mukund S.,Ley, Steven V.

, p. 1113 - 1123 (2007/10/03)

A practically simple and flexible method of making chiral tetrahydrofurans of therapeutic relevance is reported from glyceraldehyde derivatives as chiral synthons. One of the stereocentres is derived from glyceraldehyde derivatives, while the other one is introduced by Sharpless asymmetric epoxidation using either (+)- or (-)-DIPT.
