181786-38-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 181786-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,7,8 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 181786-38:
(8*1)+(7*8)+(6*1)+(5*7)+(4*8)+(3*6)+(2*3)+(1*8)=169
169 % 10 = 9
So 181786-38-9 is a valid CAS Registry Number.

Xiang, Yuejun,Schinazi, Raymond F.,Zhao, Kang
, p. 1475 - 1478 (2007/10/03)
The isoxazolidine derivative 6, prepared from an intermolecular 1,3- dipolar cycloaddition of the (5S)-unsaturated lactone 5 and N-methylnitrone, was effectively used for the synthesis of [3.3.0] bicyclic isoxazolidinyl cytidine 4a and thymidine 4b.
