Check Digit Verification of cas no

The CAS Registry Mumber 108781-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,7,8 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 108781-87:
(8*1)+(7*0)+(6*8)+(5*7)+(4*8)+(3*1)+(2*8)+(1*7)=149
149 % 10 = 9
So 108781-87-9 is a valid CAS Registry Number.

INTRAMOLECULAR CYCLOADDITIONS WITH AZOMETHINE YLIDES FOR THE SYNTHESIS OF METACYCLOPHANES

Eberbech, W.,Fritz, H.,Heinze, I.,Laer, P. van,Link, P.

, p. 4003 - 4006 (2007/10/02)

On thermal treatment of the aziridines 5a-f intramolecular cycloaddition reactions of the intermediate azomethine ylides 6 result in the formation of the metacyclophanes 7-9.For 7a and 7b the conformational barriers are estimated to be approximately 20 and 12 kcal/mol, respectively.
