Check Digit Verification of cas no

The CAS Registry Mumber 91753-15-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,5 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91753-15:
(7*9)+(6*1)+(5*7)+(4*5)+(3*3)+(2*1)+(1*5)=140
140 % 10 = 0
So 91753-15-0 is a valid CAS Registry Number.

MOLECULAR CONFORMATION AND ELECTRONIC STRUCTURE OF AZOMETHINES. VIII. DIPOLE MOMENTS OF 3,4-DIHYDROISOQUINOLINES

Pitea, Demetrio,Beltrame, Pier Luigi,Ferrazza, Alberto,Todeschini, Roberto,Favini, Giorgio

, p. 35 - 40 (2007/10/02)

The dipole moments of some methyl derivatives of 3,4-dihydroisoquinoline have been measured in benzene at 25 deg C and the experimental directions determined.The correlation with the theoretical dipole moments of the corresponding benzaldimines supports the view that the 3,4-dihydroisoquinolines can be used as models for the Z conformation of N-benzylidenemethylamines.Moreover, the differences between the dipole moment of 3,4-dihydroisoquinolines and that of the corresponding benzaldimines can be ascribed to conjugation across the -CH2-CH2- bridge.Experimental and calculated values of the methyl replacement vectors are in good agreement.
