4541-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4541-65-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,4 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4541-65:
(6*4)+(5*5)+(4*4)+(3*1)+(2*6)+(1*5)=85
85 % 10 = 5
So 4541-65-5 is a valid CAS Registry Number.

An efficient synthesis of N-methylamino acids and some of their derivatives
Spengler, Jan,Burger, Klaus
, p. 67 - 70 (2007/10/03)
N-Methylamino acid derivatives are obtained in high yield by a stereoselective one-pot procedure from hexafluoroacetone protected amino acids via N-chloromethylation and treatment with triethylsilane/trifluoroacetic acid.
