Check Digit Verification of cas no

The CAS Registry Mumber 188772-85-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,7,7 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 188772-85:
(8*1)+(7*8)+(6*8)+(5*7)+(4*7)+(3*2)+(2*8)+(1*5)=202
202 % 10 = 2
So 188772-85-2 is a valid CAS Registry Number.

Novel enantioselective synthesis of both enantiomers of furan-2-yl amines and amino acids

Demir, Ayhan S.,Sesenoglu, Oezge,Uelkue, Dincer,Arici, Cengiz

, p. 91 - 105 (2007/10/03)

A new enantioselective synthesis of furan-2-yl amines and amino acids is described, in which the key step is the oxazaborolidine-catalyzed enantioselective reduction of O-benzyl (E)- and (Z)-furan-2-yl ketone oximes to the corresponding chiral amines. The chirality of the furan-2-yl amines is fully controlled by the appropriate choice of the geometrical isomer of the O-benzyl oxime. Oxidation of the furan ring furnished amino acids in high yields.
