845300-65-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 845300-65-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,5,3,0 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 845300-65:
(8*8)+(7*4)+(6*5)+(5*3)+(4*0)+(3*0)+(2*6)+(1*5)=154
154 % 10 = 4
So 845300-65-4 is a valid CAS Registry Number.

A new class of non-racemic chiral macrocycles: A conformational and synthetic study

Gibson, Susan E.,Mainolfi, Nello,Kalindjian, S. Barret,Wright, Paul T.,White, Andrew J. P.

, p. 69 - 80 (2007/10/03)

Amino alcohols have been used to introduce non-racemic chirality into macrocycles using a modular approach that relies on a Heck macrocyclisation reaction. A wide variety of macrocycles have been synthesised, and their structures studied using X-ray crystallography and molecular modelling. A fragmentation reaction encountered during the use of (S)-1,1-dimethylvalinol revealed that carboxylic acids generate acylals under reaction conditions often used for Heck reactions.
