Opt.-inakt. 2-Phenyl-spiro<1,3>dioxan-5,2'-norborn-5'-en is a complex organic chemical compound characterized by a unique molecular structure. It features a spiro ring system, which consists of two rings sharing a common atom, in this case, a carbon atom. The compound includes a phenyl group, a benzene ring with a hydrogen atom replaced by a carbon-carbon double bond, attached to the spiro system. Additionally, it has a norbornane ring, which is a bicyclic hydrocarbon with a seven-membered ring fused to a five-membered ring. The norbornane ring is further modified with a carbon-carbon double bond at the 5' position. opt.-inakt. 2-Phenyl-spiro<1,3>dioxan-5,2'-norborn-5'-en is likely to be of interest in the field of organic chemistry, potentially for its unique reactivity or as a building block in the synthesis of more complex molecules. However, the term "opt.-inakt." suggests that it may be an inactive or non-optimal variant of a related active compound, which could imply that it is used for comparison or as a control in chemical studies.

3190-55-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3190-55-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,9 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3190-55:
(6*3)+(5*1)+(4*9)+(3*0)+(2*5)+(1*5)=74
74 % 10 = 4
So 3190-55-4 is a valid CAS Registry Number.

An efficient procedure for acetalization of carbonyl compounds with P 2O5/SiO2

Mirjalili, Bibi Fatemeh,Zolfigol, Mohammad Ali,Bamoniri, Abdolhamid,Amrollahi, Mohammad Ali,Hazar, Azizeh

, p. 1397 - 1401 (2004)

P2O5 as a dehydrating agent can be used for acetalization of carbonyl compounds. This reaction is very fast with high yield and also comparable with acetal formation by using microwave irradiation.
