140658-46-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 140658-46-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,5 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 140658-46:
(8*1)+(7*4)+(6*0)+(5*6)+(4*5)+(3*8)+(2*4)+(1*6)=124
124 % 10 = 4
So 140658-46-4 is a valid CAS Registry Number.

An efficient catalytic deprotection of thioacetals employing bismuth triflate: Synthesis of pyrrolo[2,1-c] [1,4] benzodiazepines

Kamal, Ahmed,Reddy,Reddy, D. Rajasekhar

, p. 2857 - 2860 (2003)

A simple and efficient deprotection of thioacetals has been achieved by employing bismuth triflate. This method has been effectively employed in the preparation of DNA-binding pyrrolo[2,1-c] [1,4]benzodiazepine and its dimers.

A mild and efficient dethioacetalization employing FeCl3·6H2O: Synthesis of DNA-binding pyrrolo[2,1-c][1,4]benzodiazepine ring system and its dimers

Kamal,Laxman,Reddy

, p. 1476 - 1478 (2007/10/03)

A simple and efficient dethioacetalization has been carried out by employing FeCl3·6H2O under mild conditions. This method has been investigated for the synthesis of DNA-interactive pyrrolo[2,1-c][1,4]benzodiazepine antitumour antibiotics via deprotective cyclization process.

Synthesis of sequence-selective C8-linked pyrrolo[2,1-c][1,4]benzodiazepine DNA interstrand cross-linking agents

Thurston, David E.,Bose, D. Subhas,Thompson, Andrew S.,Howard, Philip W.,Leoni, Alberto,Croker, Stephen J.,Jenkins, Terrence C.,Neidle, Stephen,Hartley, John A.,Hurley, Laurence H.

, p. 8141 - 8147 (2007/10/03)

An efficient convergent synthesis of a homologous series of C8-linked pyrrolobenzodiazepine dimers with remarkable DNA interstrand cross-linking activity and potent in vitro cytotoxicity is reported. The 'amino thioacetal' cyclization procedure was used t

Facile and efficient synthesis of the dimers of DC-81 antitumor antibiotics

Kamal,Rao

, p. 4299 - 4302 (2007/10/02)

We report an improved, economical and versatile route to the dimers of DC-81 anti-tumour antibiotics. Particularly, the protection and deprotection steps in its synthesis and in the preparation of its precursors have been avoided. There is a significant i
