853211-61-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 853211-61-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,2,1 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 853211-61:
(8*8)+(7*5)+(6*3)+(5*2)+(4*1)+(3*1)+(2*6)+(1*1)=147
147 % 10 = 7
So 853211-61-7 is a valid CAS Registry Number.

Preparation of the three C1-C7, C8-C15, and C16-N22 fragments of the Hsp90 inhibitor herbimycin A

Centonze-Audureau, Sylvie,Porée, Fran?ois-Hugues,Betzer, Jean-Fran?ois,Brion, Jean-Daniel,Pancrazi, Ange,Ardisson, Janick

, p. 981 - 985 (2005)

The construction of the three C16-N22 2, C1-C7 6 (as 23) and C8-C15 5 (as 32) segments of the Hsp90 inhibitor herbimycin A (1) is reported. l-Iodo-3-nitro-2,5-diphenol compound 2 was obtained in 55% yield for 3 steps from the commercially available diiodo derivative 7. Reaction between 1,1-dibromo-alkene 22 and vinyltin 17a using Pd(PPh3)4 or Pd(CH3CN)2Cl2/CuI/diisopropylethylamine, in toluene or DMF at 85 °C, led to enyne 23 in 63% yield (19% overall yield from isopropylidene glyceraldehyde). The synthesis of the C8-C15 sub-unit 32 was performed in 3.4% overall yield for 13 steps, from the commercially available ester 24, with a Hoppe crotylation as a key step.
