Check Digit Verification of cas no

The CAS Registry Mumber 286372-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,6,3,7 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 286372-22:
(8*2)+(7*8)+(6*6)+(5*3)+(4*7)+(3*2)+(2*2)+(1*2)=163
163 % 10 = 3
So 286372-22-3 is a valid CAS Registry Number.

Total synthesis of the ansamycin antibiotic (+)-thiazinotrienomycin E

Smith III, Amos B.,Wan, Zehong

, p. 3738 - 3753 (2007/10/03)

The first total synthesis of (+)-thiazinotrienomycin E (1), member of a novel class of cytotoxic ansamycin antibiotics, has been achieved. Key features of the synthetic strategy include (a) the efficient construction of sulfone 7 incorporating TBS protection of the aniline, (b) an improved synthesis of allyl chloride (-)-6, the advanced intermediate employed in our trienomycins A and F total syntheses, (c) application of the Kocienski modified Julia protocol to elaborate the E,E,E-triene subunit in a stereo- controlled fashion, (d) an efficient union of sulfone 7 with advanced iodide 62, and (e) Mukaiyama macrolactamization to access the thiazinotrienomycin macrocyclic ring.
