Check Digit Verification of cas no

The CAS Registry Mumber 113459-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,4,5 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 113459-78:
(8*1)+(7*1)+(6*3)+(5*4)+(4*5)+(3*9)+(2*7)+(1*8)=122
122 % 10 = 2
So 113459-78-2 is a valid CAS Registry Number.

SYNTHESIS OF TRICYCLIC COMPOUNDS VIA SEQUENTIAL INTRAMOLECULAR MICHAEL ADDITION AND ALKYLATION OF β-KETOESTER YNONES

Lavallee, Jean-Francois,Deslongchamps, Pierre

, p. 3457 - 3458 (1987)

Base-catalyzed sequential intramolecular Michael addition and alkylation of cyclic β-ketoester ynones 1 (n=1,2) produce the corresponding tricycles 3 via intermediate enone-anions 2.
