Check Digit Verification of cas no

The CAS Registry Mumber 1120367-22-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,0,3,6 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1120367-22:
(9*1)+(8*1)+(7*2)+(6*0)+(5*3)+(4*6)+(3*7)+(2*2)+(1*2)=97
97 % 10 = 7
So 1120367-22-7 is a valid CAS Registry Number.

Synthesis of Boc-amino tetrazoles derived from α-amino acids

Sureshbabu, Vommina V.,Naik, Shankar A.,Nagendra

experimental part, p. 395 - 406 (2009/06/06)

A simple route for the synthesis of Boc-protected tetrazole analogs of amino acids starting from Nα-Boc amino acids has been described. The [2 + 3] cycloaddition of Boc-α-amino nitrile and sodium azide in the presence of a catalytic amount of zinc bromide yielded the desired tetrazoles in good yields and purity. All the compounds obtained have been characterized by 1H and 13C-NMR and mass spectral studies. Copyright Taylor & Francis Group, LLC.
