49661-08-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 49661-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,6 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 49661-08:
(7*4)+(6*9)+(5*6)+(4*6)+(3*1)+(2*0)+(1*8)=147
147 % 10 = 7
So 49661-08-7 is a valid CAS Registry Number.

Conversion of Saturated Ketones into 2-Lithiodienes via N,N-Bis-Tosylhydrazone Derivatives
Magnus, Philip,Roe, Michael B.
, p. 5479 - 5482 (2007/10/02)
Saturated N-tosylhydrazones can be converted into 2-lithiodienes via N,N-bis-tosylhydrazones and elimination to an α,β-unsaturated N-tosylhydrazone, followed by the Shapiro reaction.
