Check Digit Verification of cas no

The CAS Registry Mumber 95309-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,3,0 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 95309-40:
(7*9)+(6*5)+(5*3)+(4*0)+(3*9)+(2*4)+(1*0)=143
143 % 10 = 3
So 95309-40-3 is a valid CAS Registry Number.

SYNTHESIS AND PROPERTIES OF 5-(2,3-DIPHENYLCYCLOPROPENYLIDENE)-1,6-METHANO-2(5H)--ANNULENONE (OR 10,11-DIPHENYL-4,9-METHANOQUINAREN-3-ONE). CONTRIBUTION OF HOMOBENZENE STRUCTURE ANNELATED ON QUINAREN-3-ONE

Takahashi, Kazuko,Ohnishi, Keiichi,Takase, Kahei

, p. 5685 - 5688 (2007/10/02)

The title quinarenone 2 has been prepared and proved that the three-membered ring possesses a larger diatropicity than diphenylcyclopropenone and the seven-membered ring exists in a cycloheptatriene (not norcaradiene) tautomer having a contribution of a homobenzene structure.The rotational barrier about the intercyclic bond of 2 is 13,3 Kcal/mol.
