Check Digit Verification of cas no

The CAS Registry Mumber 37753-64-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,7,5 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 37753-64:
(7*3)+(6*7)+(5*7)+(4*5)+(3*3)+(2*6)+(1*4)=143
143 % 10 = 3
So 37753-64-3 is a valid CAS Registry Number.

DIMETHYL ESTERS OF 1-AMINO-2-ARYLMETHYL CYCLOHEXYL PHOSPHONIC ACIDS. SYNTHESIS AND NMR CHARACTERIZATION

Failla, Salvatore,Finocchiaro, Paolo,Latronico, Mario

, p. 261 - 266 (2007/10/02)

Dimethyl esters of amino-arylmethyl phosphonic acids containing a cyclohexyl moiety have been prepared in good yields.All compounds are white crystalline powders very soluble in low boiling point organic solvents.Characterization by 1H-NMR techniques indicates that ortho substituents shift downfield the CH resonance, whereas ortho-carboxy groups, through hydrogen bonding with the NH group, yield a cyclic structure responsible of the dramatic downfield shift of the NH resonance.Key words: 1H-NMR characterization, crystalline, low-melting and very soluble amino-phosphonates, substrates for functionalization at the NH group.
