Check Digit Verification of cas no
The CAS Registry Mumber 273409-09-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,3,4,0 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 273409-09:
(8*2)+(7*7)+(6*3)+(5*4)+(4*0)+(3*9)+(2*0)+(1*9)=139
139 % 10 = 9
So 273409-09-9 is a valid CAS Registry Number.

A simple route to N,N-dialkyl derivatives of 2-amino-5-thiophenecarboxylates
Heyde, Cornelia,Zug, Ines,Hartmann, Horst
, p. 3273 - 3278 (2007/10/03)
Starting from acetamides 4 and using three different routes - via thioacetamides 5, 3-amino-thioacrylamides 7, or 3-chloropropeniminium salts 6 - a series of new N,N-dialkyl derivatives of 2-amino-5-thiophenecarboxylates 10 has been prepared and analytically and spectroscopically characterized.
