Check Digit Verification of cas no

The CAS Registry Mumber 1391837-97-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,1,8,3 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1391837-97:
(9*1)+(8*3)+(7*9)+(6*1)+(5*8)+(4*3)+(3*7)+(2*9)+(1*7)=200
200 % 10 = 0
So 1391837-97-0 is a valid CAS Registry Number.

Diels-Alder reactions for the construction of cyclopropylarenes

Arndt, Marion,Hilt, Gerhard,Khlebnikov, Alexander F.,Kozhushkov, Sergei I.,De Meijere, Armin

experimental part, p. 3112 - 3121 (2012/07/14)

The straightforward synthesis of new bicyclopropyl-substituted alkynes and 1,3-dienes and their application in cobalt-catalyzed Diels-Alder reactions are described. The cycloaddition processes generated the desired bicyclopropyl-substituted arene derivatives in moderate to good yields, depending on the steric congestion of the reaction partners. The regioselectivity of the cycloaddition was controlled by the ligand coordinated to the cobalt center. The cyclopropyl moiety remained unchanged over the course of the Diels-Alder reaction, indicating that no radical type intermediates were formed. Only in a single case did the DDQ oxidation of the primarily formed dihydroaromatic product lead to ring opening of a cyclopropyl subunit. In all of the other cases, cyclopropyl-modified arenes with various functionalities were obtained. Copyright
