124243-79-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124243-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,2,4 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 124243-79:
(8*1)+(7*2)+(6*4)+(5*2)+(4*4)+(3*3)+(2*7)+(1*9)=104
104 % 10 = 4
So 124243-79-4 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
