192801-39-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 192801-39-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,8,0 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 192801-39:
(8*1)+(7*9)+(6*2)+(5*8)+(4*0)+(3*1)+(2*3)+(1*9)=141
141 % 10 = 1
So 192801-39-1 is a valid CAS Registry Number.

Synthesis of anti -[2.2] (2,6) benzothiazolophane : The first example of [2.2]Benzofused heterophane
Mashraqui, Sabir H.,Nivalkar, Kishor R.
, p. 4487 - 4488 (2007/10/03)
Synthesis of the first [2.2] benzofused heterophane 8 is described via photodecarboxylation of bislactone 7. Dynamic 1H NMR studies suggest that 8 is conformationally rigid whereas 7 is conformationally mobile on the NMR time scale.
