Check Digit Verification of cas no

The CAS Registry Mumber 1284239-92-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,4,2,3 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1284239-92:
(9*1)+(8*2)+(7*8)+(6*4)+(5*2)+(4*3)+(3*9)+(2*9)+(1*2)=174
174 % 10 = 4
So 1284239-92-4 is a valid CAS Registry Number.

Determining the enantioselectivity of chiral catalysts by mass spectrometric screening of their racemic forms

Ebner, Christian,Mueller, Constanze A.,Markert, Christian,Pfaltz, Andreas

, p. 4710 - 4713 (2011/06/17)

The enantioselectivity of a chiral catalyst can be determined from its racemic form by mass spectrometric screening of a nonequal mixture of two mass-labeled quasienantiomeric substrates. The presented method opens up new possibilities for evaluating catalyst structures that are not readily available in enantiomerically pure form.
