156276-15-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156276-15-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,2,7 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 156276-15:
(8*1)+(7*5)+(6*6)+(5*2)+(4*7)+(3*6)+(2*1)+(1*5)=142
142 % 10 = 2
So 156276-15-2 is a valid CAS Registry Number.

77. Macrocyclic Imides: Versatile Synthons in Ring-Enlargement Reactions
Koch, Thomas,Hesse, Manfred
, p. 819 - 828 (1994)
Macrocyclic imides differ from phthal- or succinimids in their increased electrophilicity.This property makes them versatile synthons for reactions with several nucleophiles.If a nucleophile is attached to the N-substituent of the imide, an intramolecular
