63838-70-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63838-70-0 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 0 respectively.
Calculate Digit Verification of CAS Registry Number 63838-70:
(7*6)+(6*3)+(5*8)+(4*3)+(3*8)+(2*7)+(1*0)=150
150 % 10 = 0
So 63838-70-0 is a valid CAS Registry Number.

A New Synthesis of 3-Benzoylmethylene-2,3-dihydrofurans
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.
