78816-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78816-76-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,1 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 78816-76:
(7*7)+(6*8)+(5*8)+(4*1)+(3*6)+(2*7)+(1*6)=179
179 % 10 = 9
So 78816-76-9 is a valid CAS Registry Number.

Reactions of Substituted 1-Thiochromones and 4(1H)-Quinolones with Nucleophiles
Rudorf, W.-D.,Augustin, M.
, p. 55 - 62 (2007/10/02)
1-Thiochromone 1a and 4(1H)-quinolone 1b react with nucleophiles to substitute the methylthio group.Compounds of type 1 are suitable C3-fragments for the synthesis of novel heterocycles.Hydroxylamine leads to 2-amino-1-thiochromone-3-carboxamid
