Check Digit Verification of cas no

The CAS Registry Mumber 1265082-05-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,5,0,8 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1265082-05:
(9*1)+(8*2)+(7*6)+(6*5)+(5*0)+(4*8)+(3*2)+(2*0)+(1*5)=140
140 % 10 = 0
So 1265082-05-0 is a valid CAS Registry Number.

Oxidative isomerization of vinylidenecyclopropanes to dimethylenecyclopropanes and Bronsted acid-catalyzed further transformation

Lu, Bei-Li,Shi, Min

, p. 243 - 248 (2011/03/21)

Oxidative isomerization of vinylidenecyclopropanes 1 produces dimethylenecyclopropane aldehydes 2 in moderate to good yields using tetrapropylammonium perruthenate (TPAP)/4-methylmorpholine N-oxide (NMO) as a catalytic system and the obtained dimethylenecyclopropanes 3 can be transformed to indene derivatives smoothly in the presence of Bronsted acid (HOTf). The scope and limitations as well as the plausible mechanisms have been discussed.
