Check Digit Verification of cas no

The CAS Registry Mumber 1300748-80-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,0,7,4 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1300748-80:
(9*1)+(8*3)+(7*0)+(6*0)+(5*7)+(4*4)+(3*8)+(2*8)+(1*0)=124
124 % 10 = 4
So 1300748-80-4 is a valid CAS Registry Number.

Intramolecular Diels-Alder chemistry of 4-vinylimidazoles

He, Yong,Krishnamoorthy, Pasupathy,Lima, Heather M.,Chen, Yingzhong,Wu, Haiyan,Sivappa, Rasapalli,Dias, H. V. Rasika,Lovely, Carl J.

, p. 2685 - 2701 (2011/05/08)

An investigation of 4-vinylimidazoles as diene components in the intramolecular Diels-Alder reaction is described. In the course of these studies several parameters affecting the cycloaddition were evaluated including the nature of the imidazole protecting group, the type of dienophile and the linking group. These investigations established that amino linkers were generally more effective than either ethers or esters. In most cases, the cycloadditions were highly stereoselective, resulting in the formation of products derived from an anti transition state. The polysubstituted tetrahydrobenzimidazole core of the pyrrole-imidazole alkaloid ageliferin can be constructed through the use of pseudo dimeric 4-vinylimidazoles.
