114092-50-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 114092-50-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,0,9 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 114092-50:
(8*1)+(7*1)+(6*4)+(5*0)+(4*9)+(3*2)+(2*5)+(1*0)=91
91 % 10 = 1
So 114092-50-1 is a valid CAS Registry Number.

A Directed Aldol Approach to (+)-Milbemycin β3
Kocienski, Philip J.,Street, Stephen D. A.,Yeates, Clive,Campbell, Simon F.
, p. 2171 - 2182 (2007/10/02)
Key steps in a total synthesis of (+)-milbemycin β3 are the construction of the 1,7-dioxaspiroundecane (10) by a Lewis acid-catalysed intramolecular directed aldol reaction and the use of sulphone-based olefination reactions for the constr
