92071-97-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92071-97-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,0,7 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 92071-97:
(7*9)+(6*2)+(5*0)+(4*7)+(3*1)+(2*9)+(1*7)=131
131 % 10 = 1
So 92071-97-1 is a valid CAS Registry Number.

Stereoselective Synthesis and α-Lithiation of 1-Alkoxy Polyenes
McDougal, Patrick G.,Rico, Joseph G.
, p. 4817 - 4819 (2007/10/02)
4-Alkyl-1,4-dialkoxy-cis-2-butenes undergo a regio- and stereoselective base-catalyzed 1,4-elimination to yield all-trans 1-alkoxy dienes and trienes.These dienes and trienes are successfully lithiated α to oxygen when the alkoxy substituent is OCH2OCH3 (O-MOM).
