Check Digit Verification of cas no

The CAS Registry Mumber 98156-99-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,1,5 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 98156-99:
(7*9)+(6*8)+(5*1)+(4*5)+(3*6)+(2*9)+(1*9)=181
181 % 10 = 1
So 98156-99-1 is a valid CAS Registry Number.

A convenient one-pot synthesis and bioactivity of N-dichloroacetyl-5-aryl- 1,3-oxazolidines

Ye, Fei,Liu, Cheng-Guo,Wang, Xin-Ming,Fu, Ying,Gao, Shuang

, p. 201 - 205 (2013/09/02)

New N-dichloroacetyl-5-aryl-1,3-oxazolidines 4 were synthesized by cycloaddition reaction of an aryl substituted hydroxyalkylamine 1 with aldehyde or ketone 2, followed by acylation, without isolation of the intermediate product 3. The structures of compounds 4 were determined by spectral and elemental analyses. The structure of 4b was determined by an X-ray crystallographic analysis. The bioassay results demonstrate that these compounds could alleviate chlorsulfuron injury to maize.
