33828-75-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33828-75-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,8,2 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 33828-75:
(7*3)+(6*3)+(5*8)+(4*2)+(3*8)+(2*7)+(1*5)=130
130 % 10 = 0
So 33828-75-0 is a valid CAS Registry Number.

THERMAL SKELETAL REARRANGEMENTS OF DIMETHYL 1,2-HEPTALENEDICARBOXYLATES
Hafner, Klaus,Knaup, Guenter L.
, p. 1673 - 1676 (2007/10/02)
Thermolysis of dimethyl 1,2-heptalenedicarboxylates 1 leads by two different pathways to the corresponding 1,3-dicarboxylates 2 and to azulenes 3 - 5.The rearrangement of 1 into 2 presumably proceeds via a heptvalene intermediate 10.
