Check Digit Verification of cas no

The CAS Registry Mumber 357439-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,7,4,3 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 357439-44:
(8*3)+(7*5)+(6*7)+(5*4)+(4*3)+(3*9)+(2*4)+(1*4)=172
172 % 10 = 2
So 357439-44-2 is a valid CAS Registry Number.

Stereocontrolled synthesis of the ABCDE ring moiety of ciguatoxin CTX3C

Kobayashi, Shoji,Takahashi, Yusuke,Komano, Kazuo,Alizadeh, Babak H.,Kawada, Yuuya,Oishi, Tohru,Tanaka, Shin-Ichiro,Ogasawara, Yoshihiro,Sasaki, Shin-Ya,Hirama, Masahiro

, p. 8375 - 8396 (2007/10/03)

The ABCDE ring moiety of ciguatoxin CTX3C, a major causative agent of ciguatera poisoning, was stereoselectively synthesized. The key transformations are a chiral auxiliary-based asymmetric alkylation and an asymmetric aldol condensation, which controlled

Highly stereocontrolled synthesis of the ABCD ring fragment of ciguatoxin CTX3C

Oishi,Tanaka,Ogasawara,Maeda,Oguri,Hirama

, p. 952 - 954 (2007/10/03)

A combination of asymmetric alkylation using (1R,2S)-1-amino-2-indanol derivative as a chiral auxiliary and the ring-closing metathesis reaction was shown to be an efficient method for synthesizing the ABCD ring fragment of ciguatoxin CTX3C.
