440320-93-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 440320-93-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,0,3,2 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 440320-93:
(8*4)+(7*4)+(6*0)+(5*3)+(4*2)+(3*0)+(2*9)+(1*3)=104
104 % 10 = 4
So 440320-93-4 is a valid CAS Registry Number.

Stereochemical control in the preparation of α-amino N-methylthiazolidine masked aldehydes used for peptide aldehydes synthesis

Gros, Christel,Boulègue, Cyril,Galeotti, Nathalie,Niel, Gilles,Jouin, Patrick

, p. 2673 - 2680 (2002)

Chiral N-methyl thiazolidines masked α-amino aldehydes are used for solid phase peptide aldehyde elongation. Contrary to N-Boc-protected α-amino aldehydes, N-trityl protection secures the chiral integrity of the incoming aldehyde chiral C1′ carbon atom du
