344237-48-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344237-48-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,2,3 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 344237-48:
(8*3)+(7*4)+(6*4)+(5*2)+(4*3)+(3*7)+(2*4)+(1*8)=135
135 % 10 = 5
So 344237-48-5 is a valid CAS Registry Number.

Heterocyclic Analogues of 2,4,6-Triphenylpyrylium and 1-Benzyl-2,4,6-triphenylpyridinium
Katritzky, Alan R.,Rezende, Marcos C.
, p. 4041 - 4056 (2007/10/02)
New pyrylium perchlorates with 2-thienyl, 2-benzothiazolyl, and 2-benzimidazolyl substituents at the 2-, 4-, and/or 6-positions, were synthesised and converted into the corresponding pyridines and 1-benzylpyridinium perchlorates.
