Check Digit Verification of cas no

The CAS Registry Mumber 1218778-29-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,8,7,7 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1218778-29:
(9*1)+(8*2)+(7*1)+(6*8)+(5*7)+(4*7)+(3*8)+(2*2)+(1*9)=180
180 % 10 = 0
So 1218778-29-0 is a valid CAS Registry Number.

Facile transformation of glutamic acid into proline residue inside a tripeptide backbone

Mollica, Adriano,Stefanucci, Azzurra,Feliciani, Federica,Torino, Domenica,Cacciatore, Ivana,Pinnen, Francesco,Lucente, Gino

, p. 1333 - 1335 (2010)

In this Letter we present a simple reaction pathway which allows the conversion of the glutamic acid residue of a tripeptide into a proline residue. The reaction was performed by using Boc-Val-Glu-Phe-NH2 as a starting material and is based on a NaH-induced intraresidue alkylation under reaction conditions analogous to that adopted during the Freidinger lactams formation.
