76717-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76717-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,1 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 76717-99:
(7*7)+(6*6)+(5*7)+(4*1)+(3*7)+(2*9)+(1*9)=172
172 % 10 = 2
So 76717-99-2 is a valid CAS Registry Number.

Fabrycy, Andrzej,Wichert, Zofia
, p. 1744 - 1750 (2007/10/02)
The unknown 3-benzoylmethylene-2,3-dihydrofurans 2 has been synthesized by isomerization of ditertiary diacetylenediols 1 in the presence of mercury salts.Sometimes carbocyanine type dyes 5 are formed as by-products.
