1421692-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1421692-91-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,6,9 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1421692-91:
(9*1)+(8*4)+(7*2)+(6*1)+(5*6)+(4*9)+(3*2)+(2*9)+(1*1)=152
152 % 10 = 2
So 1421692-91-2 is a valid CAS Registry Number.

N-Alkylation of tosylhydrazones via a metal-free reductive coupling procedure
Liu, Jin-Biao,Yan, Hui,Lu, Gui
supporting information, p. 891 - 895 (2013/02/25)
A simple metal-free route for the N-alkylation of tosylhydrazones is described via the NaOMe-promoted reductive coupling of tosylhydrazones under mild conditions. A wide variety of N-alkylated tosylhydrazones were obtained in moderate to good yields.
