Check Digit Verification of cas no

The CAS Registry Mumber 120546-89-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,5,4 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120546-89:
(8*1)+(7*2)+(6*0)+(5*5)+(4*4)+(3*6)+(2*8)+(1*9)=106
106 % 10 = 6
So 120546-89-6 is a valid CAS Registry Number.

Histidine and deuterium labelled histidine by asymmetric catalytic reduction with gaseous H2 or D2; the role of strong non-coordinating acids

Cesarotti,Rimoldi,Zerla,Aldini

, p. 273 - 278 (2008/09/19)

An efficient and convenient route for the preparation of natural and unnatural histidine by asymmetric hydrogenation with rhodium-phosphine complexes is described. The reductions were performed in the presence of HBF4 to generate an essential imidazolyl cation. Stereoselective incorporation of D2 in the α,β-positions was obtained by catalytic deuteration in the presence of MeOD.
