124266-43-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124266-43-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,2,6 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 124266-43:
(8*1)+(7*2)+(6*4)+(5*2)+(4*6)+(3*6)+(2*4)+(1*3)=109
109 % 10 = 9
So 124266-43-9 is a valid CAS Registry Number.

Intramolecular Diels-Alder Reactions of Sulfur-Substituted Dienes via 3-Sulfolenes
Chou, Shang-Shing,Wey, Shiow-Jyi
, p. 1270 - 1274 (2007/10/02)
Sulfur-substituted dienes containing an unsaturated alkyl chain were readily prepared from 3-sulfolenes.The intramolecular Diels-Alder (IMDA) reaction of these derivatives was studied for the first time.A sulfonyl group on the diene was found to facilitat
