Check Digit Verification of cas no

The CAS Registry Mumber 253674-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,6,7 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 253674-40:
(8*2)+(7*5)+(6*3)+(5*6)+(4*7)+(3*4)+(2*4)+(1*0)=147
147 % 10 = 7
So 253674-40-7 is a valid CAS Registry Number.

Stereocontrolled synthesis of (-)-5,11-dideoxytetrodotoxin

Nishikawa, Toshio,Asai, Masanori,Ohyabu, Norio,Yamamoto, Noboru,Isobe, Minoru

, p. 3081 - 3084 (1999)

New derivatives of an intriguing marine natural product are now accessible. The first asymmetric synthesis of the simple tetrodotoxin analogue, 5,11-dideoxytetrodotoxin (3), was achieved. Hydroxylation at position C8 of the key intermediate 1 relied on th

Stereocontrolled Synthesis of 8,11-Dideoxytetrodotoxin, An Unnatural Analogue of Puffer Fish Toxin

Nishikawa, Toshio,Urabe, Daisuke,Yoshida, Kazumasa,Iwabuchi, Tomoko,Asai, Masanori,Isobe, Minoru

, p. 452 - 462 (2007/10/03)

8,11-Dideoxytetrodotoxin, an unnatural tetrodotoxin analogue, was synthesized in a highly stereoselective manner from a common intermediate from our synthetic studies on tetrodotoxin. The key features in the synthesis were as follows: neighboring group pa

Stereocontrolled synthesis of (-)-5,11-dideoxytetrodotoxin

, p. 4543 - 4558 (2007/10/03)

Asymmetric synthesis of (-)-5,11-dideoxytetrodotoxin, an analog of puffer fish toxin, was accomplished from a common key intermediate through a novel hydroxylation at the C-8 position with neighboring group participation of trichloroacetamide, a highly st
