197707-18-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 197707-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,7,0 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 197707-18:
(8*1)+(7*9)+(6*7)+(5*7)+(4*0)+(3*7)+(2*1)+(1*8)=179
179 % 10 = 9
So 197707-18-9 is a valid CAS Registry Number.

Total synthesis of (+)-desoxoprosopinine via the intramolecular reaction of γ-aminoallylstannane

Kadota, Isao,Kawada, Miho,Muramatsu, Yoko,Yamamoto, Yoshinori

, p. 7469 - 7470 (1997)

A stereoselective total synthesis of (+)-desoxoprosopinine starting from L-glutamic acid as a chiral source was accomplished in which the intramolecular reaction of γ-aminoallylstannane with aldehyde was used as a key step.

Asymmetric total syntheses of hydroxylated piperidine alkaloids via the intramolecular reaction of γ-aminoallylstannane with aldehyde

Kadota, Isao,Kawada, Miho,Muramatsu, Yoko,Yamamoto, Yoshinori

, p. 3887 - 3893 (2007/10/03)

Asymmetric total syntheses of (+)-desoxoprosopinine and (-)- desoxoprosophylline were accomplished, using L-glutamic acid as the chiral source, in which the intramolecular reaction of a γ-aminoallylstannane with an aldehyde was used as a key step.
