Check Digit Verification of cas no

The CAS Registry Mumber 13786-41-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,8 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13786-41:
(7*1)+(6*3)+(5*7)+(4*8)+(3*6)+(2*4)+(1*1)=119
119 % 10 = 9
So 13786-41-9 is a valid CAS Registry Number.

Total synthesis of (±) indolmycin

Shue, Youe-Kong

, p. 6447 - 6448 (2007/10/03)

A practical and short synthesis of a novel antibiotic, (±) indolmycin, has been accomplished. The overall process requires only 4 chemical steps by starting from gramine derivative 3 and oxazolinone 2.

New Total Synthesis of (+/-)-Indolmycin

Dirlam, John P.,Clark, David A.,Hecker, Scott J.

, p. 4920 - 4924 (2007/10/02)

A convergent total synthesis of the antibiotic (+/-)-indolmycin (1) is presented.N-Carbobenzoxy-3-(1-chloroethyl)indole (12) is prepared in three steps from indole-3-carboxaldehyde (9).Alkylation of the lithium anion of 2-(dimethylamino)-4(5H)-oxazolone (4) with chloride (12) provides a mixture of the (+/-)-2-dimethylamino derivative of indolmycin (13) and its diastereomer (14) in a ratio of 2.2:1.Amine exchange is effected by treatment of 13 with methylamine, affording (+/-)-1 in five steps from commercially available 9.Efforts to extend this technology toward an asymmetric synthesis of (-)-1 are described.
