Check Digit Verification of cas no
The CAS Registry Mumber 3607-17-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,0 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3607-17:
(6*3)+(5*6)+(4*0)+(3*7)+(2*1)+(1*7)=78
78 % 10 = 8
So 3607-17-8 is a valid CAS Registry Number.

Addition of water to arylidenecyclopropanes: A highly efficient method for the preparation of gem-aryl disubstituted homoallylic alcohols
Siriwardana, Amal I.,Nakamura, Itaru,Yamamoto, Yoshinori
, p. 4547 - 4550 (2003)
Arylidenecyclopropanes react with water in the presence of a catalytic amount of Cu(OTf)2 to afford the corresponding gem-aryl disubstituted homoallylic alcohols in good to excellent yields.
Strain-Promoted Oxidation of Methylenecyclopropane Derivatives using N-Hydroxyphthalimide and Molecular Oxygen in the Dark
Anderson, T. E.,Woerpel, K. A.
supporting information, (2020/07/30)
The hydroperoxidation of alkylidenecyclopropanes and other strained alkenes using an N-hydroxylamine and molecular oxygen occurred in the absence of catalyst, initiator, or light. The oxidation reaction proceeds through a radical pathway that is initiated by autoxidation of the alkene substrate. The hydroperoxides were converted to their corresponding alcohols and ketones under mild conditions.

The invention provides a simple and convenient method for preparing high-purity [3 - (dimethylamine) propyl] triphenylphosphonium bromide hydrobromide. The obtained (1,3 - bromopropyl) triphenylphosphonium bromide does not need to be separated, and is directly reacted with a dimethylamine aqueous solution in n-heptane so as to obtain [3 - 3 - (dimethylamine) propyl] triphenyl phosphonium bromide hydrobromide crude product which is obtained by hot pulping with anhydrous ethanol to obtain the high-purity [3 - 3 - (dimethylamine) propyl] triphenylphosphonium bromide hydrobromide.
