Check Digit Verification of cas no

The CAS Registry Mumber 110815-28-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,8,1 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 110815-28:
(8*1)+(7*1)+(6*0)+(5*8)+(4*1)+(3*5)+(2*2)+(1*8)=86
86 % 10 = 6
So 110815-28-6 is a valid CAS Registry Number.

A Regio- and stereocontrolled total synthesis of (-)-indolactam-V

Kogan, Timothy P.,Somers, Todd C.,Venuti, Michael C.

, p. 6623 - 6632 (2007/10/02)

(-)-Indolactam-V (IL-V) (1)-was prepared in 10 steps from L-tryptophan methyl ester in 17.1% overall yield. The key steps involve regiospecific thallation of the acylindole intermediate (4), followed by azide displacement and reduction to introduce the 13-amino group. Control of the C-11 stereocenter was achieved by SN2 displacement of the chiral inflate (10), derived from D-valine. The thallium mediated closure of dipeptide (17) did not provide an alternative route to IL-V.
