Check Digit Verification of cas no
The CAS Registry Mumber 134935-47-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,3 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134935-47:
(8*1)+(7*3)+(6*4)+(5*9)+(4*3)+(3*5)+(2*4)+(1*7)=140
140 % 10 = 0
So 134935-47-0 is a valid CAS Registry Number.

Synthesis of alkyl-1,3-dihydro-3-oxobenzo[c]oxepine-4-carboxylates
Glukhov,Kirillov
experimental part, p. 216 - 217 (2010/08/19)
Alkyl-1,3-dihydro-3-oxobenzo[c]oxepine-4-carboxylates were obtained by bromination of dialkyl-2-(2-methylbenzylidene)malonates with N-bromosuccinimide followed by the cyclization of dialkyl-2-(2-bromomethylbenzylidene) malonates.
