Check Digit Verification of cas no

The CAS Registry Mumber 209805-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,8,0 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 209805-23:
(8*2)+(7*0)+(6*9)+(5*8)+(4*0)+(3*5)+(2*2)+(1*3)=132
132 % 10 = 2
So 209805-23-2 is a valid CAS Registry Number.

A simple and efficient procedure for the synthesis of optically active 4-methoxy-α-methylphenylethylamine from tyrosine

Kohno, Harumichi,Iwakuma, Takeo,Yamada, Koichiro

, p. 1935 - 1945 (2007/10/03)

Optically active 4-methoxy-α-methylphenylethylamine (1), a useful chiral building block in medicinal chemistry, was synthesized from L- or D- tyrosine by using a simple and efficient procedure via one-pot zinc reduction of the corresponding O-tosylate (4) in the presence of H2O and NaI in pure form.
