63838-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63838-75-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,8,3 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 63838-75:
(7*6)+(6*3)+(5*8)+(4*3)+(3*8)+(2*7)+(1*5)=155
155 % 10 = 5
So 63838-75-5 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.
