Check Digit Verification of cas no

The CAS Registry Mumber 183478-96-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,4,7 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 183478-96:
(8*1)+(7*8)+(6*3)+(5*4)+(4*7)+(3*8)+(2*9)+(1*6)=178
178 % 10 = 8
So 183478-96-8 is a valid CAS Registry Number.

Enantioselective synthesis of α,α-disubstituted amino acid derivatives via enzymatic resolution: Preparation of a thiazolyl-substituted α-methyl α-benzyl amine

Spero, Denice M.,Kapadia, Suresh R.

, p. 7398 - 7401 (2007/10/03)

A new and efficient enantioselective synthesis of the (S)-α,α-disubstituted phenethylamine 1 via Lipase resolution of the esters 3 and 4 is described. The effect of pH, enzyme load, and solubilizing additives has been studied and optimized. Conversion of the carboxylic acid 10 to the desired thiazole 1 is accomplished in high overall yield via an intermediate oxazolinone 13. This facile process requires only a single chromatographic step, and multigram quantities of 1 have been prepared.
