Check Digit Verification of cas no

The CAS Registry Mumber 119098-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,0,9 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119098-03:
(8*1)+(7*1)+(6*9)+(5*0)+(4*9)+(3*8)+(2*0)+(1*3)=132
132 % 10 = 2
So 119098-03-2 is a valid CAS Registry Number.

Formal Synthesis of the Antitumour Antibiotic CC-1065

Bolton, Richard E.,Moody, Christopher J.,Pass, Martin,Rees, Charles W.,Tojo, Gabriel

, p. 2491 - 2500 (2007/10/02)

A formal total synthesis of the potent antitumour antibiotic CC-1065 (1) is described; both the cyclopropapyrroloindole (2) and the 'dimeric' pyrroloindole (3) are synthesized by routes involving vinyl azide chemistry.The cyclopropapyrroloindole (2) is prepared from 5-benzyloxy-2-bromoacetophenone (Schemes 3-5), the key steps being the formation of both indoles by decomposition of the azides (9) and (13).The dimer (3) is prepared by coupling the monomeric pyrroloindoles (25) and (27), followed by functional group transformations (Scheme 7).
