130336-21-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130336-21-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,3,3 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130336-21:
(8*1)+(7*3)+(6*0)+(5*3)+(4*3)+(3*6)+(2*2)+(1*1)=79
79 % 10 = 9
So 130336-21-9 is a valid CAS Registry Number.

RING-OPENING REACTIONS OF UNSATURATED CYCLOPROPANECARBOXYLIC ACIDS BY PYRIDINIUM CHLORIDE
Loreto, M. Antonietta,Pellacani, Lucio,Tardella, Paolo A.
, p. 379 - 381 (2007/10/02)
When heated in molten pyridinium chloride, some unsaturated cyclopropanecarboxylic acids gave ring-opening reactions followed by dimerisation and, in one case, by decarboxylation.
