83781-69-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83781-69-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,7,8 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 83781-69:
(7*8)+(6*3)+(5*7)+(4*8)+(3*1)+(2*6)+(1*9)=165
165 % 10 = 5
So 83781-69-5 is a valid CAS Registry Number.

Synthesis of 1,2,3,4-tetrahydroisoquinolines by microreactor-mediated thermal isomerization of laterally lithiated arylaziridines

supporting information, p. 1872 - 1876 (2013/04/10)

Flow chemistry: A flow-microreactor-mediated synthesis of 1,2,3,4-tetrahydroisoquinolines (THIQs) is reported (see scheme). Starting from a laterally lithiated aziridine, a tetrahydroisoquinoline lithiated at C4 was generated by thermally induced isomerization. Because the reaction temperature is a crucial parameter, the exquisite thermal control possible in a flow-microreactor system allowed for fast, efficient, and highly reproducible synthesis of functionalized aziridines or THIQs.
