76717-96-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76717-96-9 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 76717-96:
(7*7)+(6*6)+(5*7)+(4*1)+(3*7)+(2*9)+(1*6)=169
169 % 10 = 9
So 76717-96-9 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.
