Check Digit Verification of cas no

The CAS Registry Mumber 19355-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,3,5 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19355-20:
(7*1)+(6*9)+(5*3)+(4*5)+(3*5)+(2*2)+(1*0)=115
115 % 10 = 5
So 19355-20-5 is a valid CAS Registry Number.

Investigations of Quaternary Pyridinium Salts, XV. Pseudobases and Redox Products in the Reaction of Pyridinium Salts with Alcoxides

Guendel, Wolf-H.

, p. 873 - 883 (2007/10/02)

Mono- and diquaternary pyridinium salts substituted in 3-position with electron withdrawing groups, react with alcohols under basic conditions to give 6-alcoxy-1,6-dihydropyridines.Symmetric dipyridinium salts react in aqueous alkaline solution to products with 6-pyridone and dihydropyridine moiety.This redox reaction depends on the length of the bridge connecting the pyridinium rings.Pyridinium salts can be reduced by aluminiumtriisopropoxide to 1,4-dihydropyridines. - Key words: Pyridinium Salts, Insertion Reaction, Redox Reaction
