Check Digit Verification of cas no

The CAS Registry Mumber 491838-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,1,8,3 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 491838-94:
(8*4)+(7*9)+(6*1)+(5*8)+(4*3)+(3*8)+(2*9)+(1*4)=199
199 % 10 = 9
So 491838-94-9 is a valid CAS Registry Number.

Synthesis of enantioenriched 2-substituted 4-phenylbutylamines by hydrogenolysis of optically pure 6-alkoxy-5,6-dihydro-4H-1,2-oxazines

Buchholz, Monika,Hiller, Florian,Reissig, Hans-Ulrich

, p. 2838 - 2843 (2007/10/03)

Lewis acid promoted exchange of the 6-ethoxy group of 6H- 1,2-oxazines 1-3 with (-)-menthol furnished the optically active heterocycles 4-6. Diastereomers 4a and 4b, which could be separated efficiently by chromatography, were excellent substrates for hig
