Check Digit Verification of cas no

The CAS Registry Mumber 81280-29-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,8 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81280-29:
(7*8)+(6*1)+(5*2)+(4*8)+(3*0)+(2*2)+(1*9)=117
117 % 10 = 7
So 81280-29-7 is a valid CAS Registry Number.

Routes to 3aH-Indenes. Deprotonation and Methylation of some Indenones Bearing Ring Junction Substituents

Gilchrist, Thomas L.,Rees, Charles W.,Tuddenham, David

, p. 3221 - 3224 (2007/10/02)

The trienones (1), (2), and (3) have been converted into the corresponding enolate anions by reaction with potassium hydride below -10 deg C.Methyl fluorosulphonate was added to each solution: with the trienones (1) and (3), transient 3aH-indenes (4a) and
