195719-43-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 195719-43-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,7,1 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 195719-43:
(8*1)+(7*9)+(6*5)+(5*7)+(4*1)+(3*9)+(2*4)+(1*3)=178
178 % 10 = 8
So 195719-43-8 is a valid CAS Registry Number.

Autoxidation of intermediary mesoionic 1,3-oxazolium-5-olates generated from cyclic N-acyl α-amino acids
Kawase, Masami
, p. 1248 - 1253 (2007/10/03)
Mesoionic 1,3-oxazolium-5-olates (munchnones) react fairly rapidly with oxygen to give the autoxidation products when the C-4 substituent is aromatic. The autoxidation occurred in the munchnones generated from N-acyl tetrahydroisoquinoline-1-carboxylic ac
