121666-45-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121666-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,6 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121666-45:
(8*1)+(7*2)+(6*1)+(5*6)+(4*6)+(3*6)+(2*4)+(1*5)=113
113 % 10 = 3
So 121666-45-3 is a valid CAS Registry Number.

ACYCLIC STEREOSELECTION IN α-AMIDOALKYLATION REACTIONS
Harding, Kenn E.,Davis, Clark S.
, p. 1891 - 1894 (2007/10/02)
The chiral reagent 7 provides the first example of an acyclic α-amidoalkylation reagent that generates a new stereogenic center with excellent stereoselectivity, and the stereochemistry of the resulting products provides evidence that the N-acylimine inte
