88999-93-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 88999-93-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,9,9 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 88999-93:
(7*8)+(6*8)+(5*9)+(4*9)+(3*9)+(2*9)+(1*3)=233
233 % 10 = 3
So 88999-93-3 is a valid CAS Registry Number.

Mo-Based Oxidizers as Powerful Tools for the Synthesis of Thia- and Selenaheterocycles

Franzmann, Peter,Beil, Sebastian B.,Schollmeyer, Dieter,Waldvogel, Siegfried R.

supporting information, p. 1936 - 1940 (2019/01/14)

A highly efficient synthetic protocol for the synthesis of thia- and selenaheterocycles has been developed. By employing a MoCl5-mediated intramolecular dehydrogenative coupling reaction, a broad variety of structural motifs was isolated in yields up to 94 %. The electrophilic key transformation is tolerated by several labile moieties like halides and tertiary alkyl groups. Due to the use of disulfide or diselenide precursors, a high atom efficiency was achieved.

Uracil derivatives. IV. Growth-inhibitory activity against L-1210 cells of orotic acid derivatives and synthesis of 1-(β-D-ribofuranosyl)furo[3,4-d]pyrimidine-2,4,7(1H,3H,5H)-trione

Okada,Nakano,Miyake

, p. 3074 - 3083 (2007/10/02)

5-(Substituted thiomethyl)-6-carbamoyluracils (IIIb-h) and 5-(substituted thiomethyl)-uracils (Va-h) were prepared and their ability to inhibit the growth of L-1210 cells in vitro was examined. The reaction of silylated furo[3,4-d]pyrimidine-2,4,7(1H,3H,5
