7706-74-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7706-74-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,0 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7706-74:
(6*7)+(5*7)+(4*0)+(3*6)+(2*7)+(1*4)=113
113 % 10 = 3
So 7706-74-3 is a valid CAS Registry Number.

Portilla, Jaime,Quiroga, Jairo,Cobo, Justo,Low, John N.,Glidewell, Christopher

, p. o332-o333 (2007)

In the title compound, C13H10O4, prepared by the condensation reaction between phthalic anhydride and pentane-2,4-dione, one of the acetyl groups in the pentane-2,4-dione fragment is almost coplanar with the isobenzofuran ring system, while the other group is twisted out of this plane by almost 80°. The corresponding C - C and C - O distances in the two acetyl units are consistent with dipolar delocalization into the coplanar unit only. There is no supra-molecular aggregation of the mol-ecules, but a number of rather short inter-molecular contacts of C - H...O, O...O and O...C types occur.
