Check Digit Verification of cas no

The CAS Registry Mumber 1194-87-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1194-87:
(6*1)+(5*1)+(4*9)+(3*4)+(2*8)+(1*7)=82
82 % 10 = 2
So 1194-87-2 is a valid CAS Registry Number.

Nonproteinogenic Amino Acids, III. - Syntheses of the Enantiomerically Pure 2-(2-Thienyl)- and 2-(3-Thienyl)glycines. - Molecular Structure of the Intermediate Schiff's Bases

Weinges, Klaus,Brachmann, Helga,Stahnecker, Peter,Rodewald, Hans,Nixdorf, Matthias,Irngartinger, Hermann

, p. 566 - 578 (2007/10/02)

The syntheses of enantiomerically pure D-(-)- and L-(+)-2-(2-thienyl)- and 2-(3-thienyl)glycines (6a-d) are described.Preparing the amino nitriles 4 directly from 2-thiophenecarbaldehyde (1a) or 3-thiophenecarbaldehyde (1b), respectively, and (4S,5S)-(+)-5-amino-2,2-dimethyl-4-phenyl-1,3-dioxane (2), and hydrocyanic acid (one-step procedure), the aminonitriles 4a and 4b, respectively, are formed in excess.By crystallization they are obtained diastereomerically pure leading to enantiomerically pure D-amino acids 6a and 6b.If, however, the intermediate Schiff's bases 3 are isolated as crystals and then converted with hydrocyanic acid into the respective aminonitriles 4 (two-step procedure), the diastereomeric aminonitriles 4c and 4d, respectively, crystallize resulting in enantiomerically pure L-amino acids 6a and 6d.X-ray structure analyses of the Schiff's bases 3c and 3e revealed the previously postulated E-configuration of the C=N bond and its chiral shielding by the phenyl substituent at C4.
