136849-96-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136849-96-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,4 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 136849-96:
(8*1)+(7*3)+(6*6)+(5*8)+(4*4)+(3*9)+(2*9)+(1*6)=172
172 % 10 = 2
So 136849-96-2 is a valid CAS Registry Number.

Products of the Decarboxylation of Photochemically Prepared Indenecarboxylic Acid Derivatives
Schuster, C.,Bendig, J.
, p. 91 - 99 (2007/10/02)
4-(2-Diazo-1-oxo-1,2-dihydro-naphthalene-5-sulfonyl-oxy)-benzophenone (NQD-BP) was photolyzed to form 4-(3-carboxy-indene-7-sulfonyl-oxy)-benzophenone (ICA-BP).This was decarboxylated base-catalysed in ethanol leading to 4-(indene-4-sulfonyl-oxy)-benzophe
