1431879-83-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1431879-83-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,8,7 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1431879-83:
(9*1)+(8*4)+(7*3)+(6*1)+(5*8)+(4*7)+(3*9)+(2*8)+(1*3)=182
182 % 10 = 2
So 1431879-83-2 is a valid CAS Registry Number.

Synthesis of the C1-C21 domain of azaspiracids-1 and -3
Zhang, Zhigao,Ding, Yue,Xu, Jianyan,Chen, Yong,Forsyth, Craig J.
, p. 2338 - 2341 (2013/07/11)
An efficient synthesis of the C1-C21 fragment of azaspiracids-1 and -3 is described. This features a Nozaki-Hiyama-Kishi reaction to couple the AB and CD ring precursors and formation of the THF-fused ABCD trioxadispiroketal system under thermodynamic conditions.
