129333-12-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129333-12-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,3,3 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 129333-12:
(8*1)+(7*2)+(6*9)+(5*3)+(4*3)+(3*3)+(2*1)+(1*2)=116
116 % 10 = 6
So 129333-12-6 is a valid CAS Registry Number.

THE STEREOSPECIFITY OF THE CYCLOADDITION OF 5-ARYLIDENE-2-THIAZOLIDINONE-4-THIONE DERIVATIVES TO ELECTRON-DEFICIENT OLEFINS
Ead, Hamed A.
, p. 235 - 238 (2007/10/02)
The cycloadditions of 5-arylidene-2-thiazolidinone-4-thiones and their 3-phenyl derivatives 1a-d to maleic and fumaric acid esters have been investigated.The stereochemistry of the reaction products indicates a concerned mechanism.
