The chemical "C31H21O(1+)*ClO4(1-)" represents a salt composed of two ions: a cation with the formula C31H21O(1+) and an anion with the formula ClO4(1-). The cation, C31H21O(1+), is an organic molecule with 31 carbon atoms, 21 hydrogen atoms, and 1 oxygen atom, carrying a positive charge. This suggests that the molecule has lost one electron, making it a cation. The anion, ClO4(1-), is a perchlorate ion, which is a common counterion in many salts, consisting of one chlorine atom and four oxygen atoms, carrying a negative charge. The overall charge of the salt is neutral, as the positive charge of the cation is balanced by the negative charge of the anion. This salt could be a component of various chemical reactions or used in applications where its specific properties are desired, such as in electrochemistry or as a component in certain types of batteries.

3557-62-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3557-62-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,5 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3557-62:
(6*3)+(5*5)+(4*5)+(3*7)+(2*6)+(1*2)=98
98 % 10 = 8
So 3557-62-8 is a valid CAS Registry Number.

The use of N,N-dialkyltrimethylsilylamines in the synthesis of pentamethinium salts

Korinek, Marek,Rybackova, Marketa,Boehm, Stanislav

, p. 1291 - 1296 (2009)

N,N-Dialkyltrimethylsilylamines were used for the synthesis of a series of pentamethinium salts starting from 2,6-disubstituted or 2,4,6-trisubstituted pyrylium salts, N-substituted 5-aminopenta-2,4-dienals or N-substituted 5-aminopenta-2,4-dien-1-ones. The reactions proceed smoothly under mild conditions, furnishing the desired products in good yields. Georg Thieme Verlag Stuttgart.
