1646848-64-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1646848-64-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,6,8,4 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1646848-64:
(9*1)+(8*6)+(7*4)+(6*6)+(5*8)+(4*4)+(3*8)+(2*6)+(1*4)=217
217 % 10 = 7
So 1646848-64-7 is a valid CAS Registry Number.

Pyrrolidinone and piperidinone isocyanides from isocyano esters
Sidhoum, Madjid Ait,Dos Santos, Aurelie,El Kaim, Laurent,Legras, Laetitia
, p. 4949 - 4952 (2014/08/18)
The alkylation of isocyano esters with 1,2- and 1,3-dibromoalkanes affords bromo isocyanides. Under treatment with various amines the latter form new isocyano-substituted lactams, which can be further used in Passerini or Ugi reactions.
