431935-29-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 431935-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,1,9,3 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 431935-29:
(8*4)+(7*3)+(6*1)+(5*9)+(4*3)+(3*5)+(2*2)+(1*9)=144
144 % 10 = 4
So 431935-29-4 is a valid CAS Registry Number.

LiOH-mediated N-monoalkylation of α-amino acid esters and a dipeptide ester using activated alkyl bromides
Cho, Jong Hyun,Kim, B.Moon
, p. 1273 - 1276 (2002)
Selective N-monoalkylation of α-amino esters with activated alkyl bromides was studied using various alkali or alkali earth metal bases. In the production of N-monoalkylated amino ester derivatives and suppression of N,N-dialkylation, lithium hydroxide wa
